CARRIER-FREE SEPARATION OF THE INDIVIDUAL RARE EARTH RADIONUCLIDES FROM FISSION PRODUCT MIXTURES

Technical Report ·
OSTI ID:4114810
;
A procedure based on solvent extraction with diethylhexylphosphoric acid was tested for the quantitative carrierfree separation of yttrium and the rare earth group elements from other fission products. This procedure is simpler and more rapid than the previously used cation exchange resin separations of rare earths from alkali metals and alkaline earths. Subsequent quantitative carrier- free isolation of individual rare earth fission products was accomplished by their elution from cation exchange resin with alpha-hydroxyisobutyric acid at room temperature.
