- Аннотация: To solve the problem of strontium recovery from brines, polyacrylic acid cation-exchangers were used. Extraction of Sr2+ from the Na+, Ca2+ and Sr2+ mixture was accomplished in a counter-current column into which the cation-exchanger (Na+ form) and the salt solution to be separated were fed. A zone formed in the column, adjacent to the sorption front of the divalent ions, where the solution and the ion-exchanger contained concentrated strontium, separated from calcium. The solution from this zone was collected and the Sr2+ ions were eluted from the ion-exchanger in a second counter-current column by a sodium solution containing calcium. The solution eluted from the second column was returned to the first separation column and the ion-exchanger was further regenerated from the mixed Ca2+ and Na+ form to the Na+ form and returned to the separation column. All stages of the process were operated continuously and simultaneously. The extent of strontium extraction was about 98%.
