SEPARATION OF CARRIER-FREE Pa$sup 233$ FROM THORIUM NITRATE PREPARATIONS IRRADIATED BY THERMAL NEUTRONS (in Russian)

;
Carrier-free Pa/sup 233/ was separated from thorium nitrate solution by adsorption on MnO/sub 2/, complexing with cupferron, extraction with arnyl acetate, re-extraction with citric acid, and disintegrating the citric acid complex with nitric acid. A satisfactory purification from alpha and beta emitters was achieved. The prepared isotope was identifled by its half life. The method can be applied in chemical studies of protactinium and in problems related to protactinium extraction from ores as well as in Pa/sup 233/ separation from irradiated thorium. (tr-auth)
