“…Separations are also impaired by the presence of unwanted impurities in the material separated. A not unfamiliar type of contamination was reported last year by Mac-Nevin and Tuthill (13) in the separation of rhodium from iridium by controlled cathode potential techniques. After separation it was necessary to reduce the rhodium deposit in hydrogen to remove oxygen from the cathode deposit.…”

“…Rhodium may be separated from iridium by controlled potential electrodeposition under conditions described by MacNevin and Tuthill (83,84), but the deposit of rhodium is contaminated with oxide and cannot be quantitatively determined without first reducing it in hydrogen. Brouns (11) has studied the separation of cadmium and zinc with controlled potentials.…”

“…MaeXcvin and Tuthill (7) separated the two metals by electrol-ysis using a controlled cathode potential. The method requires extensive instrumentation.…”
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.
