表面活性剂对乳化液膜稳定性的实验研究

In this paper, the stability of emulsion liquid membrance with surfactanthas been studied. The emulsion liquid membrance was constructed using the N-octylaminemobilecarrier and nonionic surfactant. Different experiment conditionsfor stability of the emulsion liquid membrance with centrifugationwere studied such as different surfactant type and concentration, extraction conditions and emulsification time. The stability of the organic phase determined the degree of swelling and rupture of the emulsion liquid membrancesystem.Optimize the group characteristics and hydrolysis degreeof surfactantcan enhance the oil film strength so as to improve the stability of the system. Studying the stability of emulsion liquid membrancewas capable of providing academic and technical foundations to realize practical separation application.
