摘　　要：蒙脱土因具有层间距可调、良好的吸附性和离子交换性等优点,在污水处理上引起人们的广泛关注。天然蒙脱土存在亲水性强、吸附效率低、选择吸附性差等缺点,严重限制了蒙脱土对污水的处理能力。但天然蒙脱土经有机化改性后,可极大的提升蒙脱土的吸附性能。从表面活性剂、偶联剂及天然聚合物为有机改性剂出发,综述了近年来国内外有机蒙脱土对污水中污染物(包括重金属离子、染料、酚类化合物,多环芳烃等)处理的最新研究进展,并分析了有机蒙脱土对污染物的吸附机理,最后对有机蒙脱土复合材料未来发展方向及应用前景提出了展望。Montmorillonite has good characteristics such as adjustable layer spacing,hydrophilic expansion,strong adsorption and cation exchangeability,which has attracted considerable attention in wastewater treatment.But natural montmorillonite has some shortcomings,such as strong hydrophilicity,low adsorption efficiency and poor selective adsorption,which severely limits the application range of montmorillonite to water treatment.After organically modified natural montmorillonite,the adsorption of the organic montmorillonite is greatly enhanced.Organic modified montmorillonite can significantly improve its adsorption capacity.Embarking from the organic modifier of surfactant,coupling agent and natural polymer,the research progress of organic montmorillonite for pollutants,including heavy metal ions,dyes,phenolic compounds,polycyclic aromatic hydrocarbons,etc.in waste water treatment at home and abroad in recent years are reviewed.The adsorption mechanism of organic montmorillonite to pollutants in water is analyzed.The future development direction and application prospect of organic montmorillonite materials are prospected.
