Electrodeposition of Alpha-Emitting Nuclides from Ammonium Oxalate-Ammonium Sulfate Electrolyte
Myung Ho Lee, Cheol Ju Kim, Bong Hyun Boo
A method is described for electrodeposition of the alpha-emitting nuclides. The effects of electrolyte concentration, chelating reagent, current, pH of electrolyte, and the plating time on the electrodeposition have been investigated in an ammonium oxalate-ammonium sulfate electrolyte containing diethyl triamino pentaacetic acid in order to determine the optimum condition to plate plutonium. An optimized electrodeposition procedure for the determination of plutonium was validated by application to IAEA-Reference soils. The chemical yield in the optimized method for electrodeposition step in the environmental sample was about 7% higher than that of a Talvitie’s method. The electrodeposition procedure developed with a 242 Pu tracer was also applied to analyze the actinides such as thorium, uranium, and americium.
