Abstract: A new approach has been developed to obtain the data of solubilization kinetics,in which the micelles are not separated from the solution.The solubilization kinetics of benzene in Pluronic F127 and P123 aqueous micellar solutions have been examined by this method.The results show that the rate of benzene solubilization by both F127 and P123 micelles is significantly fast.Increasing temperature further enhances the rate of benzene solubilization.
