The method of measuring measure the molar weights of the micelle by the scatter light is presented. Based on Rayleigh scatter formula, the experimental device is designed, in which the CCD camera system is employed to collect the scattered light caused by the solution,then the signals are sent to the computer to calculate, so the molar weights of the micelle in the surfactant solution can be obtained. The result shows that the molar weight changes with the different accretion used because of different effects of sorbefaclent and increasing solvency.
