摘要：

Transport through a chloroform liquid membrane has been studied to investigate the ability of sodium lauryl sulphate reversed micelles to act as carriers for the transport of cadmium ions between two liquid/liquid interfaces. The data indicate the applicability of the facilitated diffusion model. The rate of transport of the cations correlates well with the free energy of hydration of the accompanying anion and also shows a maximum at a concentration of the surfactant in the membrane phase which equals its critical micelle concentration in aqueous solution.
