改性蒙脱石在污水处理中的应用现状及进展

Application status and progress of modified montmorillonite in sewage treatment

综述了近年来各种改性蒙脱石对于污染物(包括重金属离子、阳离子染料、阴离子染料、疏水性有机物等)在污水处理中的应用以及研究进展。从酸改性、热改性、有机改性、无机改性和有机-无机改性几个改性方法出发,介绍了各种吸附材料的开发以及研究,并系统地分析了其吸附机理和吸附特性,最后对基于蒙脱石改性材料的进展提出展望,简要讨论了其开发前景和研究方向,以期为后续的新型蒙脱石吸附材料的开发提供参考。

The application and research progress of various modified montmorillonite for pollutants(including heavy metal ions,cationic dyes,anionic dyes,hydrophobic organics,etc.)in sewage treatment in recent years are reviewed.Starting from several modification methods of acid modification,thermal modification,organic modification,inorganic modification and organic-inorganic modification,the development and research of various adsorption materials are introduced,and the adsorption mechanism and adsorption are systematically analyzed.Characteristics,and finally put forward the prospects for the progress of modified materials based on montmorillonite,briefly discussed its development prospects and research directions,in order to provide a reference for the subsequent development of new montmorillonite adsorption materials.
