Abstract
Antibiotics are used for the well-being of human beings and other animals. Detectable levels of antibiotics can be found in pharmaceutical, municipal, and animal effluents. Therefore, the treatment of antibiotic contaminated water is of great concern. In this study, we fabricated a sustainable aminated/TEMPO cellulose nanofiber (Am/TEMPO-CNF) aerogel to remove oxytetracycline (OTC) and chloramphenicol (CAP) from synthetic wastewater. The prepared aerogel was characterized using different analytical techniques such as elemental analysis, FTIR, TGA, SEM-EDS, and N2 adsorption-desorption isotherms. The characterization techniques confirmed the presence and interaction of quaternary amine -[NR3]+ and -COOH groups on Am/TEMPO-CNF with OTC and CAP, which validates the successful modification of Am/TEMPO-CNF. The adsorption process of the pollutants was examined as a function of solution pH, concentrations, reaction time, and temperatures. The maximum adsorption capacity was 153.13 and 150.15 mg/g for OTC and CAP, respectively. The pseudo-second order (PSO-2) was well fitted to both OTC and CAP, confirming the removal is via chemisorption. Hydrogen bonding and electrostatic attraction have been postulated as key factors in facilitating OTC and CAP adsorption according to spectroscopic studies. Energetically, the adsorption was spontaneous and endothermic for both pollutants. In conclusion, the efficient removal rate and excellent reusability of Am/TEMPO-CNF indicate the strong potential of the adsorbent for antibiotics' removal.

Abstract
Arsenic (As) contamination in soil-plant system is an important environmental, agricultural and health issue globally. The microbe- and sulfate-mediated As cycling in soil-plant system may depend on soil sulfate levels, and it can be used as a potential strategy to reduce plant As uptake and improve plant growth. Here, we investigated the role of soil microbes (SMs) to examine As phytoaccumulation using maize as a test plant, under varying sulfate levels (S-0, S-5, S-25 mmol kg-1) and As stress. The addition of sulfate and SMs promoted maize plant growth and reduced As concentration in shoots compared to sulfate-treated plants without SMs. Results revealed that the SMs-S-5 treatment proved to be the most promising in reducing As uptake by 27% and 48% in root and shoot of the maize plants, respectively. The SMs-S treatments, primarily with S-5, enhanced plant growth, shoot dry biomass, Chl a, b and total Chl (a + b) contents, and gas exchange attributes of maize plants. Similarly, the antioxidant defense in maize plants was increased significantly in SMs-S-treated plants, notably with SMs-S-5 treatment. Overall, the SMs-S-5-treated plants possessed improved plant growth, dry biomass, physiology and antioxidant defense system and decrease in plant shoot As concentration. The outcomes of this study suggest that sulfate supplementation in soil along with SMs could assist in reducing As accumulation by maize plants, thus providing a sustainable and eco-friendly bioremediation strategy in limiting As exposure.

Abstract
Background:
The removal of persistent organic pollutants (POPs) from the contaminated
water by employing photocatalytic adsorption is considered as one of the most emerging technologies
due to its’ cost- and energy-effectiveness. It has attracted significant attention of global researchers
to process the world’s wastewater.
Methods:
Among different adsorbents, the metal-organic frameworks (MOFs) have demonstrated
remarkable potential and a bright future perspective in the photocatalytic-based adsorptive removal
of POPs from wastewater. This review deals with the introduction of MOFs and contaminations in
wastewater, followed by the synthesis method for MOFs and their properties. The review is extended
to the review of mechanisms for the photocatalytic adsorption along with the recent progress in removal
of persistent toxic substances, pesticides, herbicides, phenols, and antibiotics. Furthermore,
the future challenges in this promising area are also discussed.
Results:
Much research work has been done in the area of photocatalytic adsorptive removal of the
POPs using the MOFs due to their significant structural and texture properties. Substantial research
efforts have been carried out to functionalize the MOFs in order to improve their adsorption potential.
Overall, this review demonstrated that the MOFs could be applied successfully for the photocatalytic
adsorptive removal of the POPs from contaminated water.
Conclusion:
Despite the bright future perspective of the MOFs, there are some issues that need to be
accounted for: The development of MOFs with redox-active metals and/or organic functionalized
ligands, MOFs application for the photocatalytic adsorptive removal of the gaseous contaminants, indepth
understanding of the mechanism of the photocatalytic adsorptive removal of the POPs, and the
application of the MOFs for photocatalytic adsorptive removal of the POPs in real environmental
conditions. The fast development of the MOFs in the recent era indicates a bright future perspective
in spite of the challenges in this area.
