Summary

Uranium or thorium separations from a number of various ions were studied by means of cation exchangers containing phosphorus in their functional group. These ion exchangers adsorb selectively only UO2 2+ or Th4+ ions from the mixture studied in a medium of >0.4 N nitric or hydrochloric acid. Several di- and trivalent cations are not sorbed under these conditions. In the absence of UO2 2+ and Th4+ ions, Me2+ may be more easily separated quantitatively from Me3+ in 0.2 N nitric or hydrochloric acid than with cation exchangers containing the -SO3H group.

Zusammenfassung

Die quantitative Trennung von UO2 2+ oder Th4+ von einer Reihe anderer Ionen wurde mit Hilfe phosphorhaltiger Kationenaustauscher untersucht. Diese Ionenaustauscher sorbieren selektiv nur UO2 2+ oder Th4+-Ionen aus einem Medium von >0,4 N HNO3 oder HCl. Eine Reihe verschiedener zwei- und dreiwertiger Kationen wird unter diesen Bedingungen nicht sortiert. Bei Abwesenheit von UO2 2+- und Th4+-Ionen kann man Me2+ in 0,2 N HNO3- oder HCl-Lösung quantitativ von Me3+ trennen, und zwar leichter als mit -SO3H-haltigen Austauschern.
