Bentonite has been selected as the candidate of backfill material for nuclear waste repositories because of its large specific area, low hydraulic conductivity, low cost, high cation exchange capacity for most of radionuclides.However, it has a negligible sorption of anionic radionuclides like79Se (half-life 3.27× 10s a) due to anion exclusion between negative charge surface of bentonite and anionic species.
