Mechanism of Palladium(II) Adsorption from Nitric Acid Solutions by a Styrene-Divinylbenzene Copolymer Functionalized with <i>N,N,N</i>-Trimethylglycine
Abstract:The ability of AMP03, a styrene-divinylbenzene copolymer functionalized with N,N,N-trimethylglycine moieties, to adsorb Pd(II) from HNO 3 solutions was investigated to elucidate the affinity of N,N,N-trimethylglycine for Pd(II). AMP03 effectively adsorbed Pd(II) from 0.10-0.50 M solutions in HNO 3 , and the adsorption ability decreased with increasing HNO 3 concentration owing to competitive adsorption of the acid. In contrast, the presence of added NO 3 − increased the Pd(II) adsorption ability of the copolym… 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.
