Abstract
The through-diffusion method and batch sorption experiments were used to explore the influence of pH on the diffusion behavior of 75Se(IV) in matrix Beishan granite (BsG). In the pH range of 2.0–8.5, the De values of 75Se(IV) in BsG decreased first and then increased with pH increasing, while the changing trend of Kd was nearly opposite. It was speculated that the influence of pH on the diffusion of 75Se(IV) in BsG was due to the joint effects of different species distribution of Se, change in surface charge of BsG and change in ionic strength at various pH values.
