Abstract:

The synthesis of quaternary ammonium Gemini surfactants and their application in adsorption of organic pollutants in water by modified clay were reviewed. Starting from the synthesis of alkyl quaternary ammonium Gemini surfactants, emphasis was given on the introduction of different types of quaternary ammonium Gemini surfactants and their synthetic routes from four aspects, i.e. changing the structures of the spacer group, hydrophobic group, cationic connection point and counterion. The application of quaternary ammonium Gemini surfactants to modify different kinds of natural clay was also reviewed. Finally, based on the development background of green chemistry, the development direction of Gemini surfactants in the future and the opportunities and challenges of their application in water pollution control were discussed.

Key words: quaternary ammonium Gemini surfactant, synthesis, modified clay, organic pollutant, adsorption
