摘要：随着经济社会的发展，污水处理问题已成为人们关注的热点。蒙脱土因孔结构丰富、储量丰富且廉价易
得而被广泛用于污水处理领域，目前关于蒙脱土吸附材料的研究多采用酸改性和有机改性等单一改性手段提升
其吸附能力，但单一改性蒙脱土存在功能单一、活性较差等问题。首先，介绍了复合改性蒙脱土的制备和应用
研究进展，重点对酸-有机改性蒙脱土、无机-有机改性蒙脱土、有机阳离子-阴离子改性蒙脱土和天然物质改性
蒙脱土进行了综述；然后，对复合改性蒙脱土对水中污染物的吸附机理进行了分析；接着，总结了光催化剂改
性蒙脱土的制备、对水中污染物的吸附机理及研究进展；最后，提出了未来复合蒙脱土研究的主要方向，指出
需要合成可利用多种方式实现对所有污染物的无差别处理，并易于从溶液中分离再生的蒙脱土。

Abstract: With the development of economy society, wastewater treatment has become the focus of
people's attention. Montmorillonite has been widely used in the field of wastewater treatment because of its
advantages of cheap, easy to obtain and abundant reserves. At present, single modification methods such as
acid modification and organic modification are used to improve the adsorption capacity of montmorillonite,
but single modification of montmorillonite has single function and poor activity. Firstly, the research
progress of preparation and application of composite modified montmorillonite is introduced. Acid-organic
modified montmorillonite, inorganic-organic modified montmorillonite, organic cationic-anionic modified
montmorillonite and natural substances modified montmorillonite are mainly reviewed. Then, the
adsorption mechanism of composite modified montmorillonite is analyzed. The preparation of photocatalyst
modified montmorillonite and its adsorption mechanism to pollutants in water, as well as research progress
are summarized. Finally, the main research direction of composite montmorillonite in the future is proposed.
It is pointed out that it is necessary to synthesize montmorillonite which can be treated indiscriminately in
various ways and can be easily separated from solution.
Key words: montmorillonite; composite; modified; adsorption; wastewater treatment
