ABSTRACT:
Actinide metal microspheres are washed with an aqueous solution of a hydrophilic surfactant having an HLB value greater than 10 and up to about 14 to remove water soluble salts therefrom and any water immiscible organic liquids adhering to the microspheres according to the process disclosed. The microspheres are prepared by dispersing an aqueous phase of the appropriate actinide metal oxide into an immiscible organic liquid in the presence of ammonia or an ammonia releasing agent under solidification conditions to form the microspheres. Uranyl nitrate and anion-deficient uranyl nitrate solutions are preferred. Improved results are obtained when the organic liquid contains a complementary lipophilic surfactant having a HLB value of no more than about 10.
