Description
Sorption properties not only depend on the radioelement and the porewater chemistry, but also on the mineral composition of the solid (bentonite, host rock). It is assumed that the sorption property of a solid is the sum of the sorption properties of the single minerals although one mineral type usually dominates. Clay minerals sorb radioelements via cation exchange or surface complexation mechanisms.
