Separation processes for actinide elements

Separation processes for the actinide elements are reviewed. The difference in oxidation states for the elements Th through Am provide the basis of their separation techniques. The transplutonium elements require multiplate chromatographic or extraction processes to separate them due to the small chemical differences of the common trivalent states. Ion-exchange and solvent extraction systems useful in laboratory tracer level separations and in multigram plant separations are described. 25 references, 9 figures, 1 table
