摘要
介绍了不同方法改性蒙脱土,包括酸活化改性、物理包覆改性、柱撑交联改性、有机季铵盐改性、聚合物改性、天然高分子改性等,综述了改性蒙脱土对水体中铬离子的吸附能力和吸附机理,并对其在含铬废水处理中的发展提出了几点建议。
The different methods of modified montmorillonite were introduced, including acid activation, physical coating, crosslinking, organic quaternary ammonium salt, polymer and natural polymer. The adsorption capacity and mechanism of modified montmorillonite for chromium ions in water were reviewed. Finally, some proposals of modified montmorillonite in chromium contai- ning wastewater treatment were put forward.
