- Abstract
Biotite is an important adsorption carrier in the constituent minerals of Beishan granite. In this work, the effects of compaction density and ionic strength on the diffusion behavior of Se(IV) and Re(VII) in biotite were studied by capillary in-diffusion method and diffusion cell through-diffusion method. When the compaction density decreases or the ionic strength increases, the apparent diffusion coefficient increases, and its values range between 10–11 and 10–9 m2/s. The relationship between De and εacc, ionic strength and εacc was fitted using Archie's law and compared with the parameters of other researchers.
