Abstract
With the increase of organic emissions in production and human life, the pollution control of organic is now an urgent problem in the environmental field. In this study, hydrothermal carbonization rice husk-loaded Al-modified biochar (Al-BC) was synthesized, and the results of scanning electron microscopy could be used to determine that Al oxide composite was loaded on the surface of the material. The specific surface area was 57.049 m2 g-1, pore volume was 0.254 cm3 g-1, and average pore diameter was 8.922 nm for BC and 109.617 m2 g-1, 0.215 cm3 g-1, and 3.969 nm for Al-BC, respectively. The control effects of these two adsorption materials on organic pollutant ibuprofen (IBU) under different pH conditions were also investigated. The research results show that the adsorption capacity of Al-BC (30.24-1.48 mg g-1) is better than BC (19.98-0.92 mg g-1) at pH from 2 to 11. Solution pH plays a crucial role in IBU adsorption from organic solution. The Langmuir fitting results show that at pH = 7, the saturated adsorption capacity of IBU on BC could reach up to 18.68 mg g-1; the adsorption capacity on Al-BC was 60.49 mg g-1. The thermodynamic parameters indicate that the adsorption is spontaneous, endothermic, and increased disorder. The adsorption material prepared in this study could provide a reference for organic pollution control in water.

[PMID: 36812996 DOI: 10.1016/j.chemosphere.2023.138190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 02/13/2023] [Accepted: 02/17/2023] [Indexed: 06/18/2023]
Abstract
Protein-like substances produced by biochemical reactions after disinfection of Zooplankton like Cyclops and humic substances in natural water are the main components of NOM (Natural organic matter). To eliminate early warning interference in the fluorescence detection of organic matter in natural water, a clustered flower-like AlOOH (aluminum oxide hydroxide) sorbent was prepared. HA (humic acid) and amino acids were selected as mimics of humic substances and protein-like substances in natural water. The results demonstrate that the adsorbent can selectively adsorb HA from the simulated mixed solution and restore the fluorescence properties of tryptophan and tyrosine. Based on these results, a stepwise fluorescence detection strategy was developed and used in natural water rich in zooplanktonic Cyclops. The results show that the established stepwise fluorescence strategy can well overcome the interference caused by fluorescence quenching. The sorbent was also used for water quality control to enhance coagulation treatment. Finally, trial runs of the water plant demonstrated its effectiveness and suggested a potential control method for early warning and monitoring of water quality.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 327:116895. [PMID: 36463841 DOI: 10.1016/j.jenvman.2022.116895] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 11/24/2022] [Accepted: 11/25/2022] [Indexed: 06/17/2023]
Abstract
Chitosan, as a bio-friendly and abundant biochar precursor, was employed to prepare cobalt-based catalyst (Co3O4@BCC) by calcination for activating peroxymonosulfate (PMS) to degrade phenacetin (PNT). Various characterization technologies and experimental designs were performed to investigate the physicochemical properties and catalytic performance of Co3O4@BCC. Approximately 99.0% of phenacetin (10 mg/L) was degraded in the system of Co3O4@BCC (0.05 g/L)/PMS (1.0 mM) within 15 min and the rate constant was 6 times higher than that in the system of Co3O4 (0.05 g/L)/PMS (1.0 mM). The results demonstrated that BCC as a carrier not only dispersed Co3O4 nanoparticles and improved the stability of catalyst, but also provided abundant electron-rich groups to facilitate the activation of PMS and the production of reactive oxygen species (ROS). Co3O4@BCC composite also exhibited good universality and reusability. More than 90% of BPA, SIZ and CAP was degraded by Co3O4@BCC activated PMS within 15 min at pH 7. The degradation rate of PNT was recovered from 90% to 98.0% via the regeneration of the used catalyst after the third run (calcination at 400 °C for 5 min). SO4•-, •OH and 1O2 were identified to be responsible for PNT degradation. Furthermore, the activation mechanism of PMS and the possible pathways of PNT degradation were reasonably speculated according to the results of electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), quenching experiments and HPLC-TOF-MS2. This study explored the application of chitosan as a recycled material and provides a feasible strategy for designing and fabricating environmentally friendly and efficient catalysts for PMS activation to degrade organic pollutants.

Abstract
The emergence of antibiotics in water has been globally recognized as a critical pollution issue. Antibiotics (such as Ciprofloxacin (CPFX) pose a serious threat to humans and to the ecosystem due to its accumulation in water sources which can lead to chronic health problems and endanger aquatic life. It is therefore crucial to properly remove them from water. In this work, a nano-composite adsorptive membrane based on Zirconium Phosphate (ZrP) adsorbent supported on Polyethersulfone (PES) was synthesized and evaluated for the removal of CPFX from synthetic aqueous solutions. The membranes described here showed a very high antibiotic removal rate. The effect of various parameters such as the initial concentration of the antibiotic, the adsorbent dosage, contact time, pH, and temperature was studied. The equilibrium data were found to reasonably best fit with the Temkin isotherm model. The membranes showed a high ciprofloxacin removal (99.7%) as opposed to (68%) when PES membrane alone was used. Moreover, a significant improvement in the membrane's water flux (100.84 L/m2.h) and permeability (97.62 L/m2.hr.bar) were noticed as opposed to pure PES membrane's flux and permeability. The adsorptive membranes were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET). The results confirmed the successful formation of ZrP nanoparticles adsorbent within the membrane matrix, and with enhanced hydrophilic properties. The membrane was successfully regenerated and reused up to 5 times. The results of this work showed the potential of such membranes for the removal of ciprofloxacin and at a high efficiency.

Abstract
The wide application of fungicides is becoming one of the main causes of water pollution. Activated carbon (AC) is a frequently-used adsorbent in water treatment. In this work, aiming to obtain a better understanding of fungicides on AC, carbendazim was selected as a model fungicide in water. The effects of AC dosage, adsorption temperature, adsorption time and pH value of solution on carbendazim adsorption by AC were investigated. When the initial concentration of carbendazim was 500 mg L-1 and the volume of wastewater was 25 mL, the optimum dosage of AC and reaction time was determined to be 0.3 g and 150 min, respectively. The pH ranging from 3.0 to 10.0 exhibited little effect on the adsorption capability of AC. The higher the adsorption temperature was, the better adsorption capacity was. Adsorption capacity could reach 32.31 mg g-1 under the optimal adsorption conditions. The kinetics study reveals that the adsorption of carbendazim occurred on the surface of adsorbent during initial stage. The adsorption data was well fitted by Langmuir adsorption isotherm, indicating that the adsorption process was monolayer adsorption. The thermodynamic experiments confirmed that the adsorption of carbendazim was an endothermic process with the coexistence of physical and chemical adsorption. Because the main components of AC used in this research work is amorphous carbon with low impurity and its surface has not been modified with additional functional groups, the conclusion of the study was easy to be replicated by repeated experiments. Therefore, the findings of this study could guide the adsorption of carbendazim onto the other kinds of AC with high specific surface area, and provide useful information for application of commercial AC in treatment of fungicides wastewater.

Abstract
Nitrite can be transformed to nitrophenolic byproducts in sulfate radical oxidation processes (SR-AOPs). These nitrophenols are highly mobile in subsurface and can potentially contaminate drinking water sources. However, their fate in a drinking water treatment remains ambiguous. Herein, the removal and transformation of four nitrophenolic byproducts formed during a heat activated peroxydisulfate oxidation process, i.e., 4-nitrophenol, 2,4-dinitrophenol, 5-nitrosalicylic acid, and 3,5-dinitrosalicylic acid, in a simulated drinking water treatment train were comprehensively examined. The removal of these nitrophenolic compounds in coagulation by either aluminum sulfate or ferric chloride ranged from 3.8% to 13.4%. In the chlorination process, 4-nitrophenol was removed only by 45.4% in 24 h at a chlorine dose of 5.0 mg/L. The removal of the other three nitrophenolic byproducts were less than 20%. Reaction between nitrophenolic byproducts and chlorine via electrophilic substitution gave rise to their chlorinated derivatives. Chlorinated nitrophenolic byproducts were more recalcitrant and toxic than their parent compounds, but still a tiny fraction of them could undergo further oxidation to form trichloronitromethane. This work implied that once nitrophenolic byproducts enter water source, they can penetrate the drinking water treatment train and react with the residual chlorine in distribution pipelines to form more hazardous byproducts. The findings raised additional concerns to the potential risk of the nitrophenolic byproducts formed in SR-AOPs.

Effect of Applied Electrical Stimuli to Interdigitated Electrode Sensors While Detecting 17α-Ethinylestradiol in Water Samples. CHEMOSENSORS 2022.

Abstract
The effect of impedance measurements of applied voltage on the detection of 17α-ethinylestradiol (EE2) in water samples using interdigitated electrodes (IDE) coated or not with thin films, is described. Firstly, the effect of immersion in EE2 aqueous solutions of layer-by-layer films prepared with poly(allylamine hydrochloride) (PAH), graphene oxide (GO), poly(1-(4-(3-carboxy-4-hydroxyphenylazo) benzene sulfonamido) 1,2 ethanediyl, sodium salt) (PAZO), polyethylenimine (PEI) and poly(sodium 4-styrenesulfonate) (PSS) was analyzed. These results demonstrated that PAH/GO films desorb during the immersion on EE2 solutions, while EE2 adsorbs on PAH/PAZO and PEI/PSS films with characteristic time values of 16.7 and 7.1 min, respectively, demonstrating that both films are adequate for the development of EE2 sensors. However, as the adsorption characteristic time is shorter, and the EE2 adsorbed amount is smaller, the PEI/PSS films are more suitable for the development of sensors. The effect of the applied voltage was analyzed using both IDEs covered with PEI/PSS films as well as those uncoated. The capacitance spectra are best fitted to analyze this effect, and the loss tangent spectra are advantageous to analyze the aqueous media. Furthermore, it was concluded that lower voltage values are best suited to perform measurements of this nature, given that higher voltages lead to less reliable results and cause irreparable damage to the sensors.

Abstract
As a natural source of visible light and a type of renewable energy, solar energy is extensively used in the field of photochemistry. In this study, solar was employed to activate persulfate (PS) to degrade typical micropollutants. The removal kinetics of aspirin (ASA) and flunixin meglumine (FMME) in the solar/PS system were well fitted by pseudo-first-order models (R2 > 0.99). In the system containing 1.0 mM PS activated by solar irradiation at a fluence of 1.14 × 10-4 E·m-2·s-1, 72.6% and 97.5% of ASA and FMME were degraded, and the corresponding kinetic constants were 6.8-9.8 × 10-2 and 1.6-9.8 × 10-1 min-1, respectively. Qualitative and quantitative analyses of the reactive oxygen species (ROS) indicated that sulfate radical (SO4·-) played a major role in degradation, with the maximum contributions of 77.7% and 88.8% for the degradation of ASA and FMME, whereas the maximum contributions of hydroxyl radical (·OH) were only 11.6% and 6.5%, respectively. The contributions of singlet oxygen (1O2) were less than 15% at pH 5.5, but increased to 25.6% and 45.5% at pH 8.5, respectively. Solar/PS pre-oxidation increased disinfection byproducts (DBPs) (95.8% for trihalomethanes (THMs) and 47.9% for haloacetic acids (HAAs) at pH 7.0) after chlorination in deionized water, and an opposite trend was found in systems coexisting with natural organic matter (NOM). Residual PS after oxidation resulted in a high aquatic toxicity, with an inhibition rate of 18.70% to algae growth. Economic analysis showed that the electrical energy per order values of the system ranged from 23.5 to 86.5 kWh·m-3·order-1, indicating that the solar/PS system shows promise for practical applications.

Adsorption and fouling behaviors of customized nanocomposite membrane to trace pharmaceutically active compounds under multiple influent matrices. WATER RESEARCH 2021; 206:117762.

Abstract
Rare information is available on fouling behavior of customized nanofiltration (NF) membrane evoked by pharmaceutically active compounds (PhACs) under real multiple influent matrices pretreated by ultrafiltration module beforehand. To this end, a novel tight NF membrane with excellent perm-selectivity and antiadhesion was fabricated and used to assess its separation performance/mechanism and fouling behavior to a broad range of small molecular PhACs in the context. The adsorption ratio results revealed that the affinities between five selected PhACs and the customized nanocomposite membrane surface were all much weaker (below 5.5%) than the solute-solute interacting forces (between 23.6 and 83.2%), whether for natural or synthetic complex micropollutants. The predominant membrane fouling could be interpreted by the incomplete blocking model in the permeation of both influent conditions. For neat nanocomposite membrane, the order of critical factors important on separation mechanism was electrostatic effect, adsorption and steric hindrance. The fouling layer seemed to act as a secondary separating layer for those negatively charged or hydrophilic PhACs, but showed the cake enhanced concentration polarization effect for the neutral and hydrophobic ones. This study provides valuable insights for defining PhACs fate and NF membrane fouling behavior to fit increasingly stringent criteria for wastewater treatment.

Abstract
A systematic literature review of publications from 2000 to 2020 was carried out to identify research trends on adsorbent materials for the removal of caffeine from aqueous solutions. Publications were retrieved from three databases (Scopus, Web of Science, and Google Scholar). Words "adsorption AND caffeine" were examined into titles, abstracts, and keywords. A brief bibliometric analysis was performed with emphasis on the type of publication and of most cited articles. Materials for the removal of caffeine were classified according to the type of material into three main groups: organic, inorganic, and composites, each of them subdivided into different subgroups consistent with their origin or production. Tables resume for each subgroup of adsorbents the key information: specific surface area, dose, pH, maximum adsorption capacity, and isotherm models for the removal of caffeine. The highest adsorption capacities were achieved by organic adsorbents, specifically those with granular activated carbon (1961.3 mg/g) and grape stalk activated carbon (916.7 mg/g). Phenyl-phosphate-based porous organic polymer (301 mg/g), natural sandy loam sediment (221.2 mg/g), composites of MCM-48 encapsulated graphene oxide (153.8 mg/g), and organically modified clay (143.7 mg/g) showed adsorption capacities lower than those of activated carbons. In some activated carbons, a relation between the specific surface area (SSA) and the maximum adsorption capacity (Q max) was found.

Abstract
Understanding and acquiring knowledge about the adsorption of pharmaceuticals on carbon-based nanomaterials (CNMs) is imperative to the chemical engineering applications of CNMs, as well as to risk assessment and pollution control of both CNMs and pharmaceuticals. A computational assessment of the mechanism and thermodynamics of the adsorption of 18 most common pharmaceuticals (acetaminophen, acetylsalicylic acid, atenolol, caffeine, carbamazepine, clofibric acid, diclofenac, fenofibric acid, fluoxetine, gemfibrozil, ibuprofen, ketoprofen, naproxen, phenazone, primidone, propranolol, salicylic acid, tramadol) on four different CNMs (pristine/functionalised graphene and carbon nanotube) in two different solvents (water and n-octanol) was provided. We show that the adsorption of pharmaceuticals on pristine CNMs is controlled by dispersion forces, π-interactions and hydrophobic interaction. On the other hand, adsorption on functionalised CNMs is controlled by hydrogen bonding and Coulombic interactions. Furthermore, we demonstrate how functionalization of CNM, CNM curvature and background solution properties modulate the intensity of non-covalent interactions and their contribution towards adsorption free energy. With this knowledge, we pinpoint functionalised graphene at environmental pH as the most effective setting for the removal of a given set of pharmaceuticals from water and wastewater. Finally, we show that CNMs may transport pharmaceuticals into living organisms and release them in nonpolar mediums such as cellular membranes and fat cells.

Abstract
In this study, we investigated the synergetic effects of coexisting electrolytes and dissolved organic matter (DOM) on Carbamazepine (CBZ) and Ciprofloxacin (CIP) adsorption on the 1D flexible structure of MIL-53(Al) and 3D rigid structure of UiO-66(Zr). The effects of electrolytes on the adsorption of CBZ and CIP on 1D flexible framework of MIL-53(Al) were more significant than those observed from the 3D framework of UiO-66(Zr). The presence of sulfate, nitrate, and phosphate anions indicates high potential to promote the adsorption of CBZ and CIP onto MIL-53(Al) and UiO-66(Zr) because of the decrease of solubility and strengthening of electrostatic interactions by substitution of oxo-anions at the metal complex node via covalent bonding. The lower hydration energy of the potassium ion enhanced CBZ adsorption on MIL-53(Al), while the higher hydration energy of calcium and magnesium ions reduced the adsorption capacity of CBZ and CIP on MIL-53(Al) and UiO-66(Zr). CBZ interacted with fractionated humic acid better than CIP. High-density carboxylic and aromatic functional groups on humic acid ensured that only humic acid larger than 1KDa was adsorbed by MIL-53(Al). Tryptophan-like and humic acid-like DOM were both detected in real hospital effluent, and their effects on CIP and CBZ adsorption onto MIL-53(Al) were investigated. The presence of tryptophan did not affect CBZ adsorption on MIL-53(Al) (except when coexisting with calcium ions). Conversely, tryptophan interfered with CIP adsorption. The presence of humic acid lower than 1KDa promoted the adsorption of CBZ and CIP by increasing the breathing effect of MIL-53(Al)'s 1D flexible framework. The presence of humic acid with molecular size greater than 1KDa enhanced both CBZ and CIP adsorption via a multilayer adsorption mechanism.

Abstract
Natural organic matter (NOM), such as humic acids, fulvic acids, and tannic acids, is ubiquitous in water bodies and hinders the photodegradation of pharmaceuticals and personal care products (PPCPs). We prepared titanium incorporated hierarchical diatoms as a novel photocatalyst to selectively remove PPCPs (triclosan, bisphenol A or BPA, and N, N-Diethyl-meta-toluamide or DEET) in the presence of NOM (humic acid). Diatom (Stephanodiscus hantzschii) grown in a titanium(IV) bis(ammonium lactato) dihydroxide solution integrated 7.2% ± 1.4% (mass fraction) of titanium in their cell wall and formed silica-titania frustules. The photodegradation of triclosan, BPA, and DEET by both silica-titania frustules and titania nanopowder (a control photocatalyst) follows pseudo-first-order kinetics. Under ultraviolent light irradiation, the titanium-content-normalized pseudo-first-order removal rate constants of triclosan, BPA, and DEET by silica-titania frustules were 3, 4, and 4-times those by titania nanopowder, respectively, at a humic acid concentration of 10 mg•L-1. Incorporation of titanium did not alter the morphology and hierarchical nano/microstructures of the diatom. The silica-titania frustules were rich in nanopores with a diameter of 20 ± 4 nm (mean ± standard deviation), allowing PPCPs with a small molecular weight (typically < 600 g•mol-1) to pass through while efficiently rejecting NOM with high molecular weights. The silica-titania frustules with hierarchical nano/microstructures served as a prefiltration unit by selectively allowing PPCPs to pass through the nanopores and are therefore promising for photodegradation and environmental remediation applications.

Anti-inflammatory drugs degradation during LED-UV 365 photolysis of free chlorine: roles of reactive oxidative species and formation of disinfection by-products. WATER RESEARCH 2020; 185:116252.

Abstract
Light-emitting diode (LED) is environmentally friendly with longer life compared with traditionally mercury lamps. This study investigated the non-steroidal anti-inflammatory drugs (NSAIDs)- phenacetin (PNT) and acetaminophen (ACT)- removal during LED-UV (365 nm) photolysis of free available chlorine (FAC). Degradation of PNT and ACT during LED-UV365/FAC treatment at pH 5.5-8.5 followed the pseudo-first order kinetics. The presence of hydroxyl radicals (·OH), reactive chlorine species (RCS), and ozone (O3, transformed from O (3P)) were screened by using scavengers of ethanol (EtOH), tert-Butanol (TBA), and 3-buten-2ol, and 4-hydroxy-2,2,6,6-tetramethylpiperidine (TEMP), and quantified by competition kinetics with probing compounds of nitrobenzene (NB), benzoate acid (BA), 1,4-dimethoxybenzene (DMOB). Higher pH would lead to decrease of ·OH contribution and an increase of FAC contribution to PNT and ACT degradation. It has been determined that the contribution of O3 to degradation of PNT and ACT was less than 5% for all pHs, and O3(P) reacts toward EtOH with second-order constant of 1.52 × 109 M-1s-1. LED-UV365/FAC system reduced the formation of five typical CX3-R type disinfection by-products (DBPs) as well as the cytotoxicity and genotoxicity of water samples at pH 5.5 and 8.5, compared with FAC alone. The decrease of DBPs formation resulted from fast FAC decomposition upon LED-UV365 irradiation. A feasible reaction pathway of DBPs formation in the LED-UV365/FAC system was examined with density functional theory (DFT). For FAC decay during LED-UV365/FAC with effluent from wastewater, the residual FAC in 15 min was 0.8 mg/L (lower than limit of 0.2 mg/L) once initial FAC was 2.0 mg/L. The results indicate that more tests on the balance of target pollutant removal efficiency, residual FAC and cost should be explored in LED-UV365/FAC system for application.

Abstract
Electrochemical decomposition of lipopolysaccharide (LPS) was firstly investigated over titania nanotubes (TNTs) arrays electrode. The TNTs layer of this electrode consisted of numerous tubular structures which arranged tightly, and the average diameter of each nanotube is 100 ± 5 nm. The degradation of LPS and polysaccharides followed pseudo-first-order kinetics. The optimal LPS removal ratio was nearly 80 %. The endotoxin toxicity of LPS steadily decreased during the electrolysis process. The acute toxicity of the intermediates increased suddenly at the beginning of electrochemical degradation process (< 5 min), then maintained high inhibition ratio (> 95 %) for about 150 min, and decreased significantly (< 10 %) after electrolysis for 240 min. After 20 min of electrolysis, LPS with molecular weight of 116,854 Da was transformed into small molecular compounds with molecular weights of 59,312 - 12,209 Da. Possible degradation and detoxification mechanisms of LPS including electric-field-force-driving accumulation, adsorption and direct electron transfer on TNTs arrays electrode, and •OH oxidation were proposed. This study underscores that electrochemical technique can be applied to eliminate and decrease the toxicity of LPS from contaminated water.

Abstract
The excessive use of acetochlor (ACT), a commonly used herbicide with latent endocrine disrupting functions, causes surface water pollution. The efficient removal of ACT from contaminated water supplies is of paramount importance. In the current work, 3,5-Bis(trifluoromethyl)phenyl isocyanate (BTP) was successfully anchored onto Cr-MIL-101 walls via covalent incorporation to afford Cr-MIL-101-BTP as a novel adsorbent for the high-efficiency removal of ACT in aqueous solutions. The kinetic adsorption process, adsorption isotherms, adsorbent regeneration, and key parameters, such as adsorbent dosage, pH value, and ionic strength, for the adsorption of ACT were studied. Results showed that a pseudo-second-order rate equation effectively describes the adsorption kinetics. The Langmuir model exhibited a better fit to adsorption isotherm than the Freundlich model. Given the π-π stacking and hydrogen bond interaction, the adsorption capacity in Cr-MIL-101-BTP approached a maximum of 312.5 mg/g for ACT, which was considerably higher than the adsorption capacities of many other reported adsorbents. The excellent adsorption characteristics of Cr-MIL-101-BTP toward ACT were preserved in a wide pH range and high concentration of background electrolytes. In addition, the result showed that partition coefficient (PC) of Cr-MIL-101-BTP was 356.14 mg/g/μM at 5 mg/L of ACT concentration, which was found as the outperformer in all tested subjects. The ACT adsorption capacity of Cr-MIL-101-BTP at the breakthrough point was greatly influenced by initial concentration, and could be described by the Thomas model. Regeneration experiments indicated that the Cr-MIL-101-BTP was recycled at least six times without significant loss of adsorption capacity. Moreover, Cr-MIL-101-BTP did not show cytotoxic activity against the tested HepG2 cell lines and did not pose serious risks to Daphnia carinata survival (48 h LC50 = 446.6 μg/mL). These results prefigured the promising potential of Cr-MIL-101-BTP as a novel adsorbent for the efficient removal of ACT from aqueous solutions.

Abstract
The aim of this study is to evaluate the performance and antifouling properties of polyethersulfone (PES) membrane incorporated with dual nanofiller, zinc oxide (ZnO) and multi-walled carbon nanotube (MWCNT). The synergistic effect of the these nanofillers in PES membrane is studied by blending different ratio of ZnO/MWCNT nanofiller into the PES membrane. The fabricated membranes were characterized in terms of cross-section and surface morphology, surface hydrophilicity, pore size and porosity. The filtration performance of the membranes was tested using 50 mg/L humic acid (HA) solution as model solution. SEM image and gravimetric evaluation reported that the incorporation of both MWCNT and ZnO into the PES membrane improved porosity significantly up to 46.02%. Lower water contact angle of PES membrane incorporated with equal ratio of MWCNT and ZnO (PES 3) revealed that it has neat PES membrane properties and more hydrophilic membrane surface than single filler. PES 3 outperform other membranes with excellent HA permeate flux of 40.00 L/m2.h and rejection of 88.51%. Due to hydrophilic membrane surface, PES 3 membrane demonstrate efficient antifouling properties with lower relative flux reduction (RFR) and higher flux recovery ratio (FRR). PES 3 also showed notable antibacterial properties with less bacterial attached to the membrane compared to neat PES membrane (PES 0).

Abstract
Aluminum (Al) salts are widely used as coagulants to remove phosphorus (P) in water treatment. However, the relationship between P and Al species and the underlying coagulation mechanisms is rarely studied. Currently, water eutrophication is a serious issue, and therefore advanced P removal is extremely necessary. Herein, the orthophosphate removal behavior of Al coagulants with various species distributions was investigated. The results showed that AlCl3·6H2O (AC) had a more pronounced P removal efficiency than polyaluminum chloride (PACl). Medium (Alb or Al13) and high polymeric species (Alc) played a more significant role in removing P than monomeric species (Ala). During coagulation, adsorption onto flocs was the dominant P removal mechanism, which could be categorized as multilayer adsorption. Although the adsorption kinetics showed that physical adsorption best described the adsorption mechanism for AC and PACl, it is worth noting that chemical adsorption also occurred during P removal by AC because of the formation of the AlPO4 precipitate. This could be because of the strong complex adsorption between the in situ Al13 species and P. Based on the excellent P removal performance, we believe these findings will have a large potential for application in advanced P removal in water treatment.
