Surfactant is an amphiphilic molecule, its adsorption at interfaces plays a very important role and has numerous applications in many chemical fields. Currently, most of the literatures are often limited to investigate the interfacial tension and the rheological properties of surfactant. Although some researchers use adsorption model but it is just one or two of them, lacking of systematic summary of a variety of interfacial adsorption models and their comparison.In this review, the commonly used models to describe interfacial absorption dynamics, such as Langmuir absorption model, Frumkin absorption model, Rearrangement absorption model and rigorous Rearrangement absorption model were described. The characteristics and the relationships of these models were discussed as well. Besides, the applications of these adsorption models in studying interfacial absorption of surfactants were introduced. Adsorption model is designed to provide the theoretical basis and theoretical guidance in the study of interfacial adsorption of surfactant. In addition, the development perspectives of these adsorption models in studying the adsorption of surfactants are also discussed.
