“…For instance, a back extraction column has been proposed for recycling benzene using an automated on-line solvent extraction for the determination of As and Sn by ETAAS. 123 For on-line waste treatment, different strategies and reagents are used in order to destroy or passivate the toxic species in the effluent. Metal ions must be passivized by adding a reagent in the waste stream.…”

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.
