BACKGROUND Magnetic chitosan was crosslinked with graphene oxide and a magnetic chitosan–graphene oxide composite was synthesized and characterized. The composite was used for the removal and extraction of aromatic amines like aniline, N,N‐dimethylaniline and N,N‐diethylaniline. RESULTS Experimental factors affecting the adsorption process such as solution pH, time of contact, amount of adsorbent, initial concentration of analyte and temperature of solution were studied. The maximum adsorption capacity was found to be 7.55 mg g−1 for aniline, 6.96 mg g−1 for N,N‐dimethylaniline and 6.86 mg g−1 for N,N‐diethylaniline using pH 7 at room temperature. Kinetic and adsorption isotherm models were applied to the data which showed the best fit of experimental data to pseudo‐second‐order kinetic model and Langmuir isotherm for all three analytes. CONCLUSIONS The adsorption process was found to be spontaneous and exothermic as revealed by thermodynamic study. The maximum recoveries for aniline, N,N‐dimethylaniline and N,N‐diethylaniline were 98.56%, 97.05% and 95.26%, respectively. Successful application of the adsorbent was found for spiked aqueous samples. © 2022 Society of Chemical Industry (SCI).

“…Efficient methods are also systematically sought to remove phenolic compounds from aqueous solutions (e.g., sewage), classified as potential endocrine-disrupting chemicals (EDCs), such as bisphenol and octylphenol. These compounds cause exogenous endocrine disruption in the neurological, reproductive, and immune systems, even in very small amounts, and are classified as highly toxic pollutants [ 48 ]. Balahouane et al [ 49 ] used polymer inclusion membranes with calix[4]resorcin arene derivatives as the carrier, CTA as the polymer matrix, and 2-NPOE as a plasticizer to eliminate bisphenol A (BPA) from synthetic wastewater (model solutions containing bisphenol A) and to determine the process parameters that most affect its performance.…”

Pollution of the environment, including water resources, is currently one of the greatest challenges due to emerging new contaminants of anthropogenic origin. Of particular concern are emerging organic pollutants such as pharmaceuticals, endocrine disruptors, and pesticides, but also other industrial pollutants, for example, synthetic dyes. The growing demand for environmentally friendly and economical methods of removing emerging contaminants and synthetic dyes from wastewater resulted in increased interest in the possibility of using techniques based on the application of polymer inclusion membranes (PIMs) for this purpose. PIM-based techniques are promising methods for eliminating emerging contaminants and synthetic dyes from aqueous solutions, including wastewater, due to high efficiency, membranes versatility, ease/low cost of preparation, and high selectivity. This review describes the latest developments related to the removal of various emerging contaminants and synthetic dyes from aqueous solutions using PIMs over the past few years, with particular emphasis on research aimed at increasing the effectiveness and selectivity of PIMs, which may contribute to wider use of these methods in the future.

“…However, these measures do not solve the immediate problem, i.e., the presence and accumulation of pesticides in different environments such as aqueducts, rivers, lakes, and other freshwater sources. In this sense, bio-nanotechnology provides us with strategies to adsorb and entrap pesticides within polymer nanoparticles [ 18 , 19 , 20 , 21 , 22 ]. The biosorption process refers to the unique ability of certain biomolecules or polymeric matrices to effectively capture and accumulate specific ions or molecules from water-based solutions.…”

Pesticides have a significant negative impact on the environment, non-target organisms, and human health. To address these issues, sustainable pest management practices and government regulations are necessary. However, biotechnology can provide additional solutions, such as the use of polyelectrolyte complexes to encapsulate and remove pesticides from water sources. We introduce a computational methodology to evaluate the capture capabilities of Calcium-Alginate-Chitosan (CAC) nanoparticles for a broad range of pesticides. By employing ensemble-docking and molecular dynamics simulations, we investigate the intermolecular interactions and absorption/adsorption characteristics between the CAC nanoparticles and selected pesticides. Our findings reveal that charged pesticide molecules exhibit more than double capture rates compared to neutral counterparts, owing to their stronger affinity for the CAC nanoparticles. Non-covalent interactions, such as van der Waals forces, π-π stacking, and hydrogen bonds, are identified as key factors which stabilized the capture and physisorption of pesticides. Density profile analysis confirms the localization of pesticides adsorbed onto the surface or absorbed into the polymer matrix, depending on their chemical nature. The mobility and diffusion behavior of captured compounds within the nanoparticle matrix is assessed using mean square displacement and diffusion coefficients. Compounds with high capture levels exhibit limited mobility, indicative of effective absorption and adsorption. Intermolecular interaction analysis highlights the significance of hydrogen bonds and electrostatic interactions in the pesticide-polymer association. Notably, two promising candidates, an antibiotic derived from tetracycline and a rodenticide, demonstrate a strong affinity for CAC nanoparticles. This computational methodology offers a reliable and efficient screening approach for identifying effective pesticide capture agents, contributing to the development of eco-friendly strategies for pesticide removal.
