Abstract
Studies on liquid-liquid extraction of trace level cerium and gadolinium,141Ce and153Gd, from HCl and HNO3 media with liquid cation exchanger, HDEHP reveal that a quantitative separation of the elements from an admixture of the two radioisotopes can be achieved with 0.1% HDEHP and 0.01N HCl. The condition is also valid for separation of trace amount of153Gd from bulk or macro quantity of cerium.
