文摘
- •
The diffusion coefficients of selenite in purified bentonite were investigated.
- •
The apparent diffusion coefficient would be explained by Archie's law and is proportional to exponentiation of porosity.
- •
The activation energy of selenite in purified bentonite was 20 ± 4 kJ mol−1.
- •
The activation energy was similar to the activation energies of oxo-anions in free water.
