Department of Chemistry, Japan Atomic Energy Research Institute, 319-11, Tokai-mura, Ibaraki-ken, (Japan) aut Simultaneous determination of neptunium, plutonium, americium and curium using coprecipitation with bismuth phosphate [Elektronische Daten] [T. Kimura] Radiochemical studies of the coprecipitation behaviour of neptunium, plutonium, americium and curium with bismuth phosphate were carried out on the basis of the effect of the following variables: kinds of acid, acidity, and amounts of bismuth and coexisting other elements. Simultaneous determination of the actinide elements using the coprecipitation was accomplished by adding 1 mg of bismuth at 0.2M phosphoric acid and by direct measurement of alpha spectrum of the precipitates. The order of the coprecipitation yields of the elements was also discussed by the difference of both the oxidation states and sulfate complex formation.
