[PMID: 36174758 DOI: 10.1016/j.envres.2022.114317] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 08/30/2022] [Accepted: 09/07/2022] [Indexed: 06/16/2023]
Abstract
In the current research work, the activated carbon synthesized from the plant species Delonix regia is doped with iron oxide nanoparticles and enforced as a nanosorbent for the effective extermination of Tartrazine (TAR) and Methylene blue (MB) dyes. This nanosorbent is prepared from the bark powder of the Delonix regia and subjected to chemical activation; Furthermore, the synthesized biosorbent were characterized using FTIR, SEM, TGA, and XRD to understand their functional properties and structural morphology. The optimum effectiveness adsorption of Tartrazine and Methylene blue has been investigated by using different key parameters. The conclusions have shown the highest removal percentage at a pH of 3 and 6 for Tartrazine and Methylene blue, respectively. For the various initial concentrations, the adsorption percentage reached equilibrium after 60 min and 90 min for TAR and MB. The adsorption equilibrium values were applied to various isotherms models. The adsorbent showed a higher removal capacity of 357.142 mg g-1 and 147.058 mg g-1 and for MB and TAR respectively. The kinetic data were best fits to pseudo second order model. The thermodynamic parameters indicated that this adsorption process was found to be spontaneous, exothermic and feasible at different temperatures. These results have shown that the prepared adsorbent is an environmentally friendly and suitable material for the elimination of TAR and MB from water systems.

[PMID: 35248568 DOI: 10.1016/j.envres.2022.113020] [Citation(s) in RCA: 43] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 02/14/2022] [Accepted: 02/22/2022] [Indexed: 06/14/2023]
Abstract
In the present study, banana peel waste was used as a suitable source for biochar production. The banana peel biochar (BPB) was modified using Fe3O4 magnetic and ZIF-67 nanoparticles. The modification of the BPB surface (4.70 m2/g) with Fe3O4 and Fe3O4/ZIF-67 significantly increased the specific surface of the nanocomposites (BPB/Fe3O4: 78.83 m2/g, and BPB/Fe3O4/ZIF-67: 1212.40 m2/g). The effect of pH, temperature, contact time, adsorbent dose, and concentration of Cd2+ on the efficiency of the Cd2+ adsorption was explored. Maximum adsorption efficiencies for BPB (97.76%), BPB/Fe3O4 (97.52%), and BPB/Fe3O4/ZIF-67 (99.14%) were obtained at pH 6, Cd2+ concentration of 10 mg/L, times of 80 min, 50 min, and 40 min, and adsorbent doses of 2 g/L, 1.5 g/L, and 1 g/L, respectively. Thermodynamic measurements indicated that the process is spontaneous and exothermic. The maximum capacity of Cd2+ adsorption using BPB, BPB/Fe3O4, and BPB/Fe3O4/ZIF-67 were obtained 20.63 mg/g, 30.33 mg/g, and 50.78 mg/g, respectively. The Cd2+ adsorption using magnetic nanocomposites followed the pseudo-first-order kinetic model. The results showed that studied adsorbents especially BPB/Fe3O4/ZIF-67 have a good ability to adsorb-desorb Cd2+ and clean an effluent containing pollutants.

[PMID: 34399259 DOI: 10.1016/j.chemosphere.2021.131810] [Citation(s) in RCA: 33] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 07/26/2021] [Accepted: 08/04/2021] [Indexed: 06/13/2023]
Abstract
In this study, the composite materials using different ratios of biochar (BC) to nano-hydroxyapatite (nHAP) were prepared for the remediation of lead (Pb) and cadmium (Cd) contaminated water and soil. The sorption and the immobilization experiments indicated a higher sorption capacity and immobilization efficiency of Pb compared to those of Cd. The characteristics of XRD, FTIR, SEM, and XPS manifested that dissolution-precipitation, cation exchange, complexation, and cation-π interaction were the main four mechanisms for the sorption of Pb2+ and Cd2+ using composite material PC1 (nHAP/BC = 1/1). From semi-quantitative analysis, the mineral effect accounted for the majority of the immobilization of Pb and Cd. Due to obvious Pb-precipitates in the sorbed material, dissolution-precipitation primarily affected the sorption of Pb using PC1, while the immobilization of Cd was mainly attributable to cation exchange. Such results corresponded to the stable Pb-precipitates and unstable Cd-compounds in soil, among which the latter was prone to be released into the environment. The sorption capacity in aqueous solutions and the immobilization efficiencies in the soil for both Pb and Cd increased with the addition of nHAP, which were linearly correlated to the nHAP proportion in the composite materials. In future practical applications, the percentages of composite materials can be designed according to the specific pollutant concentration. This study sheds light on the explicit immobilization mechanisms for Pb and Cd in aqueous solutions to better understand their behaviors in the soil remediated by relevant materials.

Influence of the Alcoholic/Ethanolic Extract of Mangifera indica Residues on the Green Synthesis of FeO Nanoparticles and Their Application for the Remediation of Agricultural Soils. Molecules 2021; 26:molecules26247633. [PMID: 34946715 PMCID: PMC8708852 DOI: 10.3390/molecules26247633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 12/06/2021] [Accepted: 12/10/2021] [Indexed: 11/16/2022] Open
Abstract
The green synthesis of iron oxide nanoparticles (FeO NP) has been investigated using the extract in absolute ethanolic and alcoholic solvents 96% from the peel of the mango fruit (Mangifera indica), thus evaluating the influence of the type of solvent on the extraction of reducing metabolites. A broad approach to characterization initially controlled by UV-vis spectrophotometry has been directed, the formation mechanism was evaluated by Fourier transform infrared spectroscopy (FTIR), the magnetic properties by characterization by Physical Property Measurement System (PPSM), in addition to a large number of techniques such as X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (DRX), transmission electron microscopy (TEM/STEM), electron energy loss spectroscopy (EELS), and Z potential to confirm the formation of FeO NP. The results suggest better characteristics for FeO NP synthesized using 96% alcoholic solvent extract. The successful synthesis was directly proven in the removal of metals (Cr-VI, Cd, and Pb) as a potential alternative in the remediation of agricultural soils.

Abstract
In this present study, a novel and low cost surface improved material was prepared from the farm waste material (Borassus flabellifer male inflorescence) and its surface was enhanced by the sulphuric acid treatment to intensify the Ni(II) ions adsorption. The adsorption individualities such as availability of functional groups, essential elements and the exterior side and structural properties of the material were assessed by the FT-IR, EDX, SEM and XRD investigation. The impact of varied adsorption influencing parameters on Ni(II) ions adsorption was studied and optimized as pH - 6.0, biosorbent dosage - 1.5 g/L, contact time - 60 min and temperature - 303 K via batch adsorption examination. Modeling examinations were carried with varied adsorption isotherm (Langmuir, Freundlich, Fritz-Schlunder and Temkin) and kinetic models (Pseudo-first order, Pseudo-second order and Elovich kinetics). Thermodynamic studies were carried out at varied Ni(II) ions concentrations (25 mg/L - 150 mg/L) and temperatures (303 K-333 K) to explain the nature of Ni(II) ions adsorption on Borassus flabellifer male inflorescence. The prepared material has shown the most suitable Ni(II) ions adsorption results for the Langmuir isotherm (R2 = 0.9808) and Pseudo-first order kinetic models (R2 = 0.9735 for 25 mg/L). Thereby, the modeling study revealed that the prepared material has received the Ni(II) ions adsorption capacity (qm) value of 20.31 mg/g and the Ni(II) ions adsorption was physisorption. Thermodynamic results demonstrated that the Ni(II) ions adsorption was immediate, exothermic and favorable at low temperature.

Modeling analysis on the effective elimination of toxic pollutant from aquatic environment using pyrolysis assisted palmyra palm male inflorescence. ENVIRONMENTAL RESEARCH 2021; 197:111146.

Abstract
In this study adsorption of Cd(II) ions using the pyrolysis assisted Palmyra palm male inflorescence (PAPMI) was systematically examined. A batch adsorption study was carried out to determine the type of interactions and removal efficiency which is based on the surface property of PAPMI. The diverse parameters which affect the adsorption performance of PAPMI for Cd(II) ion removal were optimized: biosorbent dose - 1.25 g/L, pH - 6.0, temperature - 303 K, initial cadmium ions concentration - 50 mg/L and contact time - 40 min. Pseudo-first order kinetics and Langmuir isotherm models were more suitable to describe the adsorption kinetics and isotherm, respectively. Therefore, modeling studies portrayed the present Cd(II) ions adsorption on PAPMI as monolayer adsorption occurs on the homogeneous surface and follows the physisorption mechanism. The maximum adsorption capacity of the synthesized PAPMI was examined as 233.2 mg/g from the equilibrium isotherm investigation. Based on the calculated thermodynamic parameters (ΔGo, ΔHo and ΔSo) values, the present Cd(II) ions adsorption on PAPMI was explicated as feasible, and exothermic. The outcome proposed that Palmyra palm male inflorescence can be a suitable adsorbent for expulsion of Cd(II) ions from aqueous environment. In the interim, the utilization of pyrolysis assisted is a viable and fast uptake innovation for the removal of heavy metals from water environment.
