Abstract
A process for the removal of anionic radionuclides from spent ion exchange resin comprising mixing at least one reagent with said resin in solution to form a first mixture, and removing the anionic radionuclides from the spent ion exchange resin to produce radionuclide-bound reagent, wherein the reagent has the following general formula: (R1)n H(4-n) X Y wherein R1 is a linear or branched C1-C12 alkyl, a linear or branched C1-C12 alkenyl, cycloalkyl, phenyl, or a linear or branched C1-C12 alkyl or alkenyl substituted with cycloalkyl or phenyl; 1 ≤ n ≥ 4; X is N, P, or As; and Y is Cl, Br, I, bromate, bisulfite, benzenesulfonate, salicylate, citrate, and phenate. The radionuclide can be removed from the radionuclide-bound reagent via a precipitating agent, thereby regenerating the reagent for subsequent use in the process.
