“…The use of small, spherical and homogeneous-diameter resins enhanced SFs by 3 to 4 orders of magnitude74. Zeman et al 75 studied the effects of resin type, size and cross-linking and a-HIB concentration on RE separations and reported that Domx 50 Wx8 100-200 mesh was the optimal choice for these separations. Dowex 50 Wx12 gave larger SFs but more diffuse peaks than Dowex 50 Wx4.…”

“…46 indium with EDTA was separated from other cations and also from excess of unreacted indium on a Dowex-50 cation-exchange resin. Preliminary extraction of indium with dithizone improved the selectivity.…”

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.
