Radiolytic and chemical Degradation of strong acidic Ion-Exchange resins: study Of the ligands formed

摘要

The formation of water-soluble organic ligands by radiolytic and chemical degradation of several strong acidic ion-exchange resins was investigated under con- ditions close to those of the near field of a cementitious repository. The most important degradation products were studied and their complexing properties evaluated. Irradiation of strong acidic cation exchange resins (Powex PCH and Lewatite S-100) resulted in the for- mation of mainly sulfate and dissolved organic carbon.
