Abstract
A process for the separation of actinide ions from aqueous, basic, carbonate containing solutions with the use of basic ion exchangers. The actinide ions are sorbed at a weakly basic anion exchanger comprised of a polyalkene matrix provided in the majority with tertiary and in the minority with quaternary amino groups. The charged ion exchanger is separated from the solution and then the actinide ions are eluted from the exchanger with nitric acid.

Process for separating actinide ions from an aqueous basic, carbonate containing solution with a basic ion exchanger comprising:
- sorbing the actinide ions at a weakly basic anion exchanger comprising a polyalkene matrix provided in the majority (more than 50% of the total number of amino groups) with tertiary and in the minority with quaternary amino groups, separating the charged ion exchanger from the solution, and then eluting the actinide ions from the ion exchanger with nitric acid.
