PROCESS FOR SELECTIVELY SEPARATING PLUTONIUM FROM URANIUM AND OTHER METALS

摘要

A process for selectively separating plutonium from uranium and other metals is disclosed wherein, in order to precipitate and remove the pertaining complexes, use is made of a sufficient quantity of a cationic compound containing at least one group adapted to assert affinity to polar surfaces and containing a radical which has little affinity to water, e.g. surface active agents and the like, and use is made of the capability of Pu4+ and U4+ to form nitrato-complexes and of the capability of Pu4+ and UO22+ to form sulfato-complexes.
