Abstract:The treatment of effluents containing heavy metals by adsorption, using biopolymers as adsorbents have been widely investigated in order to obtain a material with high efficiency, readily available and economically feasible. As a natural adsorbent of metal ions, chitosan has shown good results, but the modification of its structure and crosslinking with chemical agents provides greater efficiency in adsorption processes. In this work, we have investigated the adsorption of Cu 2+ and Cr 3+ ions on chemically mo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
