Abstract
FIELD: chromatographic separation of actinides. SUBSTANCE: method is carried out by sorption on the sulfocationite in cupric or nickel form following by successive elution with solution of diethylenetriaminepentaacetate cobalt at concentration 10-20 g/l at pH 2.3-2.4 and then - with solution of diethylenetriaminepentaacetate alkaline metal or ammonium at concentration 10-20 g/l at pH 6.8-7.3. Coefficient of berkelium purification is 10, berkelium yield is 100% . EFFECT: increased yield and purification degree of berkelium from californium. 1 tbl
