摘要
The effect of Bacillus spp. on Re(VII) and Se(IV) diffusion in compacted GMZ bentonite was investigated by a through-diffusion method. Bacillus spp. had no significance effect on the effective diffusion coefficient (D-e) and the accessible porosity (epsilon(acc)) of Re(VII), whereas a decrease of D-e and an increase of distribution coefficient (K-d) were observed for Se(IV). Moreover, Archie's law and an exponential decay equation were employed to fit the D-e value of Re(VII) and Se(IV).
