Abstract:Separation of europium (Eu 3+ ) and yttrium (Y 3+ ), using a solvent impregnated resin (SIR) containing 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester, coated by water-soluble chitosan crosslinked by glutaraldehyde, was investigated. Coating of the SIR successfully suppressed leakage of the extractant during adsorption processing. Adsorption of Eu 3+ with both coated and uncoated SIRs was progressed with Langmuir mechanism, and the maximum adsorption amount of Eu 3+ at equilibrium pH = 2.27 was… 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.
