摘要
蒙脱石(MMT)作为一种天然矿物材料,具有高比表面积和良好的阳离子交换能力,在污染物治理方面具有良好的发展前景。蒙脱石纳米片(MMTNS)是由MMT剥层制备获得的二维材料,优化了MMT的部分特性,在水环境修复领域具有更高的应用价值。综述了MMTNS的制备方法及其结构性能变化,并梳理了MMTNS在水环境治理领域的研究进展,通过对MMTNS改性进一步提高其污染物去除效能,结合实例展示蒙脱石纳米复合材料在水污染修复领域的应用。
Montmorillonite(MMT),a natural mineral,has high specific surface area and good cation exchange capability,making it promising in pollution control.Montmorillonite nanosheets(MMTNS),which are exfoliated from MMT,show some better characteristics.Therefore,MMTNS have a higher value in water remediation application.In this study,the preparation methods of MMTNS,as well as the change of structure and properties,were reviewed.MMTNS were modified to enhance the ability in pollutant removal efficiency further.The research progress on MMTNS in water treatment was discussed and some application examples were illustrated.
