对不同比例的下列表面活性剂混合物水溶液的表面张力作了测定:C10H21OSO3Na(简称10CH)-C12H25OSO3Na(简称12CH),C7E15COONa(简称7CF)-10CH及7CF-12CH.自溶液的表面张力一浓度关系求得临界胶团浓度(cmc).

Surface tension of the solution of the following surfactant mixtures with different molar proportions has been determined(at 30℃);C10H21OSO3Na(10CH)-C12H25OSO3Na(12CH),C7F15COONa(7CF)-10CH and 7CF-12CH.The critical micellar concentrations(cmc) have been obtained from the surface tension-concentration relations.It has been found that the omo of 10CH-12CH mixture(C12) can be well related to the cmo of the singlo component(omc01 and omc02) by the equation derived from thermodynamics and the theory of olectrical double layer with the "Phase separation" model.
