Novel separation technique using liquid surfactant membranes containing mobile carrier has recently attracted practical interest through individual ion recovery from brines and metallurgical wastes. In this paper, as a basic study of the selective separation and concentration of metal ion using liquid surfactant membranes, the extraction of copper with benzoylacetone was carried out using a stirred transfer cell. The effect of chelating complex formation on extraction rate was examined experimentally and theoretically. As a result, it became clear that the experimental results were explained by a diffusion model accompanied by the formation of chelating complex. In addition, the rate constant of complex formation and the mass transfer coefficient of benzoylacetone into aqueous phase were obtained.
