In order to study the eventual reduction of plutonium from the VI-valent atate to the IV-valent state, in sulfuric medtum under the influence of its own alpha radiation or of the gamma rays from a cobalt-60 source, a method for preparing pure hexavalent plutonium and two methods for analyzing solutions containing tetravalent and hexavalent plutonium simultaneously were developed. Hexavalent plutonium was prepared by anodic oxidation at a platinum electrode. Study of the oxidation yield as a function of various factors made it possible to define experimental conditions giving complete oxidation. For concentrations in total plutonium greater than 1.5 x 10/sup -3/, determination of the two valences, IV and VI, was carried out by spectrophotometry at two wavelengths. For lower concentrations, the determination was done by counting, after separation of the tetravalent plutonium in the form of fluoride in the presence of a carrier (auth)
