Abstract: This paper gives the experimental setup and the theory of surfactant-selective membrane electrode applying in the study of the interaction between the surfactants and the polymers. The applications of the surfactant-selective membrane in studying the interactions between ionic surfactants and different kinds of polymers are also reviewed. The results have indicated that the binding isotherm of surfactant on polymer is a very good method to investigate the interactions between surfactants and polymers. The earlier studies mainly concerned with surfactants-polymers systems at relatively higher polymer or surfactant concentrations. However, the introduction of the surfactant selective membrane electrode has allowed the extension of these studies to very low surfactant concentration.
