Abstract:For alleviating both of the environmental and resource-depletion problems related to heavy metals, the authors examined the heavy-metal adsorption and desorption functionalities of some hydrogels. It was found that the functional hydrogels can capture the heavy metals more efficiently than other adsorbents, and besides, some of them can desorb the adsorbed heavy metal with the efficiency of~ 100%. From these experimental results, the authors have proposed a new heavy-metal recycling system in which the hydroge… 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.
