Keywords:TRU wastes, Geological disposal, Anion adsorbent

In order to improve the retardation performance of buffer materials for geological disposal, the adsorption characteristics of anion nuclides for the candidate adsorbents were evaluated. The results showed that monosulfate, IXE-700F, was superior in adsorption of anions in a geological disposal environment.
