AB  - The sorption behavior of Se(IV) on Grimsel granodiorite and its main minerals, plagioclase, K-feldspar, quartz and biotite, were investigated in Grimsel groundwater simulant in a large Se concentration range (from 1.66 x 10(-10) M to 1 x 10(-3) M). Experimental results show that the distribution coefficients (K-d values) of Se (IV) on the rock and mineral samples increased with the decreasing of Se(IV) concentration. The sorption of Se (IV) on biotite has the largest K-d value in low concentrati...
