Fundamental investigations on preparation of Am(VI) in nitric acid solutions of various concentrations were carried out in order to develop a partitioning method for americium from high level liquid waste generated from the reprocessing of spent fuel. A mixture of ammonium peroxodisulfate and silver nitrate was used as oxidizing reagent. The yields of Am(VI) were determined as a function of the concentrations of nitric acid (0.01-2M) and oxidizing reagent (0.1-2M) and temperature (55-85°C). The yield of Am(VI) decreased with increasing concentration of nitric acid. In 1M nitric acid solution, increasing the concentration of ammonium peroxodisulfate resulted in increased of Am(VI) yield. When 1.5M ammonium peroxodisulfate and 0.01M silver nitrate were used, 90% of the americium in 1M nitric acid solution was oxidized to the hexavalent state at 85°C.
