The method of measuring the apparent molar mass of micelles by light scattering is introduced. Based on the Rayleigh scattering formula, the experimental device is designed and debugged. The scattered light generated by the laser passing through the test liquid is sampled by a CCD camera system. , The apparent molar mass of micelles in the surfactant solution was determined.The results showed that the apparent molar mass changed with the adsorption and solubilization of micelles due to the different additives in the system
