    摘要： 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.

    摘要： Processes for removing heat stable amine salts from a contaminated aqueous amine solution are proposed comprising passing a feedstream of the contaminated aqueous amine solution in an electrodialysis zone comprising at least one repeat unit with an amine solution compartment for receiving the feedstream, a waste compartment, and an anion source compartment receiving an anion source stream or a bi-polar membrane disposed for providing anions balancing the heat stable anions. Monitoring of an anion source-related parameter being correlated to the anion source concentration of the anion-depleted source stream, or of a waste parameter being correlated to an acid concentration of the waste stream, is performed to further adjust an addition of the anion source or a removal of the waste stream in accordance with the monitored parameter.
