Kinetic and competitive effects of sorption on multi-element migration through crushed granite and biotite gneiss in Ca-HCO3-SO4 type groundwater

Kinetic and competitive effects of sorption on multi-element migration through crushed granite and biotite gneiss in Ca-HCO3-SO4 type groundwater

Crystalline rock is used as the host rock for the disposal of high-level radioactive waste. Two cationic elements (Cs(I) and Ni(II)) and three anionic elements (Se(IV/VI), Mo(VI), and U(VI)) were selected to comprehensively evaluate the sorption behaviors of these radionuclides on crystalline granit...

Zusammenfassung:Crystalline rock is used as the host rock for the disposal of high-level radioactive waste. Two cationic elements (Cs(I) and Ni(II)) and three anionic elements (Se(IV/VI), Mo(VI), and U(VI)) were selected to comprehensively evaluate the sorption behaviors of these radionuclides on crystalline granite and biotite gneiss. The anionic elements showed weak sorption (log Kd (L·kg−1)
