摘要
本文对高纯度十二烷基聚氯乙烯醚硫酸盐(C_(12)EO_nSO_4M)和纯皂为两元表面活性剂混合水溶液体系,在气/液界面上和胶束中有关的物化性能进行了一系列测试,通过对这些物化数据的处理和比较,探讨了这类两元混合体系在气/液界面上和胶束中相互作用的机理,找出了两元表面活性剂混合体系降低表面张力之效能大小与β_(?)和β_M的关系,定性地解释了表面活性剂效率与效能不总是平行的原因。
Abstract: The physicochemical properties of aqueous solution of binary surfactant systems of pure polyoxyethylene dodecyl sulfates(C12EOnSO4M,M = Na,NH4; n = l,2,3)and pure soaps(Sodlum laurate or palmitate)are studied. A series of parameters of interaction at the gas/ liquid interfaces(βs)and in the micelles(βM)are obtained, and the interaction mechanism of these systems are investigated.The relations between the effectiveness of surface tension reduction and βs and βM are found.Also.it is explained qualitatively that the efficiency and effectiveness of surfactant are not always consistent.
