摘要
非理想二元混合表面活性剂体系混合吸附单层的组成随体相组成的变化可通过单点参数法确定。这使得能够根据构成二元混合体系的单一表面活性剂的γ～ｌｏｇＣ关系和混合体系的一个表面张力数据，应用所建立的表面张力方程预测不同体相组成和浓度的非理想二元混合体系的表面张力。应用于一些不含外加无机盐和含过量外加无机盐的阴离子／阳离子二元混合体系，理论预测结果与实验结果完全符合。
The dependence of the binary mixed surfactant monolayer composition on that of bulk solution can be defined by measuring only one surface tension of mixture solution.Thus it is possible to predict the surface tensions of binary mixtures with different bulk composition and concentration by the surface tension equations established,based on the γ logC relationships of the individual surfactant constituting the mixture and the measured one surface tension of binary mixture Good agreements have been obtained between predicted and experimental results for some binary anionic/cationic surfactant mixtures without or with excess inorganic electrolyte.
