Surfactant adsorption behavior and its influencing factors in soil
Abstract:The amphiphilic nature of surfactant makes it has excellent interfacial activity. Adsorption is an important way for surfactant to change the interfacial properties and exhibit interfacial activity. Studying the adsorption of surfactants in soil porous media is of great significance for application of surfactants in the field of soil remediation. In this article, adsorption behavior of surfactants in soil porous media at home and abroad was reviewed including the adsorption mechanism, adsorption kinetics and thermodynamics of surfactant and the factors influencing adsorption process.
Keywords: surfactant soil porous media adsorption influencing factors
