Abstract
Designing an emulsified matrix formulation in the laboratory, the ratios of the emulsifier span-80 and T-152 were 1:0, 2:1, 1:2, 0:1 respectively. Then the preparation was added by 0.04% Fe2+ impurities emulsion matrix. Based on the water-soluble test method, we used ultrasonic instrument to focus on emulsion matrix containing Fe2+ impurities. The results show that the crystallization amount of emulsion matrix by adding Fe2+ is more than that of not adding Fe2+ .Impurities Fe2+ has damaging effects on the stability of its interface membrane. At the same time, ultrasound can accelerate the speed of demulsification of emulsion matrix. As composite emulsifiers span-80: T-152=1:2, the stability of emulsion matrix is the best.
