Abstract:From the perspective of environmental protection, high removal rate, reusability and degradability, Amino-functionalized porous hydrogel material P-(EA-β-CD/KHA/AC) was synthesized by introducing ethylamino cyclodextrin, humic acid and activated carbon, using polyacrylic acid as the carrier. The gel materials before and after adsorption were characterized by FTIR, XRD and XPS. The removal of organic matter (MB) and heavy metal ions (Cr (VI)) showed high adsorption capacity. At 298K and pH 8, the adsorption cap… 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.
