ANION EXCHANGE OF METAL COMPLEXES ⅩⅢ. THE ACTINIDE (Ⅲ) - NITRATE SYSTEMS

摘要

Anion exchange distribution data were obtained for a number of trivalent actinide ions (Pu, Am, Cm, Cf and Es) in lithium nitrate solu-tions. The distribution coefficients are comparable with those of the lanthanide group, so that no group separation is possible, but within the actinide group, an efficient separation of americium and curium was found. Extraction behaviour by long chain amines followed that of the lanthanides, but in reverse atomic number order. A second power dependence of distribution coefficients on amine concentration was found.
