Heavy metal ion pollution in water and soil is a formidable environmental problem. Due to their desired heavy metal capture capacity and excellent chemical and physical stability, resin chelating ligands have been widely used in heavy metal adsorption. In this Review, we outline the latest progress in chelating resin adsorbents toward heavy metals. This paper reviews the methods of selectively separating the target ions in various solutions and screens the excellent performances of chelating resins; the types and synthesis methods of chelating resins are also summarized. Different adsorption mechanisms existing between chelating resins and heavy metal ions are summarized, and the influencing factors of the adsorption processes are analyzed. On this basis, we propose the opportunities, challenges, and prospects faced by researchers studying chelating resin materials in the adsorption of heavy metals, and the reasonable design of advanced chelated resin-based adsorption systems should achieve an eco-friendly and sustainable environment.

“…Ahmed and colleagues [5] discovered an ion-exchange copolymer made of formaldehyde, o-toluidine, and 8-hydroxyquinoline that has increased metal ion absorption capacity and functions as a superior ionexchanger for metal ion removal. Gurnule and associates produced a copolymer resin from 2-hydroxy acetophenone and adipamide with tioxane when Pb 2+ ions were utilised as an ion exchanger in place of Cu 2+ , Ni 2+ , Cd 2+ , Zn 2+ , and Fe 3+ ions [6][7]. Additionally, a few harmful bacteria and fungi were inhibited by the produced copolymer.…”

Composites are viewed as promising advanced materials because of their superior features, including enhanced flame retardancy, density, relatively large surface areas, strength and thermomechanical/optoelectronic/magnetic capabilities. 2-amino 6-nitrobenzothiazole, oxamide, and formaldehyde has been used for the synthesis of copolymerizing polycondensation technique, and newly synthesized copolymer with activated charcoal was used to synthesize its composite. Several physicochemical techniques, and Ultraviolet-visible, SEM, TGA, and FTIR techniques, have been utilized to illustrate the produced copolymer and its composite. The non-aqueous conductometric titration was used to determine the molecular weight of the 2-amino 6-nitrobenzothiazole-oxamide-formaldehyde copolymer.based on TGA data, thermal stability of the composite is higher than copolymer, possibly because there are more carbonized residues. Based on Ea values determined by Sharp-Wentworth and Freeman-Carroll technique for copolymer and its composite, it is observed that they are in good agreement with each other. It is abundantly obvious from the results of the sequence of reaction that the decomposition reaction roughly follows a first-order kinetics. The composite's higher surface area, porous makeup, and smaller particle size may have contributed to its superior performance. The copolymer and its composite have better heat stability.
