Description
A simple solvent extraction method has been developed for the separation of 90Y from 90Sr. Crown ether dissolved in chloroform was used as a selective reagent and organic picrate anion was chosen as a counter ion. The effect of various factors on the extraction equilibrium constant of strontium log Kex = 9.15 was obtained from the study of the distribution coefficient versus to crown ether concentration. The separation method was simple, resulted high purity (>99.9%) and quantitative yield, and took less than half an hour. (author) 27 refs.; 4 figs.; 4 tabs
