PROCEDE POUR SEPARER DES IONS ACTINOIDES DE SOLUTIONS AQUEUSES, BASIQUES, CONTENANT DES CARBONATES

摘要

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.
