Abstract
The mobility and concentration of aqueous Se species in soil water and ground water are strongly affected by coprecipitation reactions with minerals such as calcite, CaCO3. Here we present the results of an XAF S investigation to determine how the tetrahedral SeO42- species is acc ommodated in the bulk calcite structure. Our results show that the SeO 42- substitutes for trigonal CO32- groups in octahedral sites.
