The radiochemical separation of bismuth by amalgam exchange in an aqueous sulfuric acid system was critically evaluated. The bismuth amalgam exchange step is followed by a back-extraction with saturated cupric sulfate in 1.0N nitric acid for selective removal of bismuth from the mercury phase. Bismuth yields of 97.5% were obtained with less than 0.1% contamination from most typical elements. Mineral acids below 2.0M do not affect the exchange. At room temperature the overall separation requires about 10 minutes; at higher temperatures, about 4 to 5 minutes. (auth)
