The separation of strontium and cadmium ions in a system containing ethylenediaminetetraacetic acid (EDTA) as a complexing agent has been studied using a three-compartment electrolytic cell. The results suggest that under the influence of an electric field, Sr ions were exclusively transported to the cathode as positively charged uncomplexed cations while cadmium ions removed from the middle compartment of the electrolytic cell migrated to the anode as negatively charged complexes. The effect of the EDTA complexing agent on the separation was studied within the pH range 2-4 at 100 mA (12.4 mA cm −2 ).
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.
