The effect of solution ionic strength on the transport and release of montmorillonite colloid in saturated porous media
离子强度对蒙脱石胶体在饱和多孔介质中运移与释放的影响

The migration and immobility of pollutants is affected by the deposition and release of colloid in porous media. In this study, a series of simulation experiments were conducted to investigate the migration and release of montmorillonite in porous media at different solution ionic strength (IS). The results showed that the transport and release of montmorillonite were significantly influenced by solution IS. The deposition of colloid increased with the increasing IS, while the release of colloid adsorbed in the porous media decreased with the decreasing IS, and the total amount of released colloid increased with the changing times of IS.
