The degradation of strong basic Anion exchange resins and Mixed-Bed ion-exchange resins: Effect of degradation products On radionuclide speciation

摘要

The most important water-soluble products of the ra- diolytic degradation of anion exchange resins in a ce- mentitious environment are ammonia and methylamines. These ligands do not form complexes with most radio- Nuclides. Exceptions are Ni, Ag, and Pd, which form Strong complexes with amines. Other degradation products of anion and mixed-bed Ion-exchange resins are of no importance concerning the Complexation of trivalent radionuclides. This is shown Indirectly by adsorption experiments: the degradation Products do not have a significant effect on the adsorp- Tion of Eu(III) on calcite.
