| 摘 要： | 对于三元两相不互溶体系的界面吸附用Langmuir模型进行计算，以Margules方程修正体系的非理想性，由此导出计算界面张力的两参数模型。计算值与93个实验数据和文献数据比较表明，该模型可较好地描述体系界面张力随溶质浓度的变化情况。

| Abstract: | Interfacial adsorption in ternary liquid-liquid insoluble systems was modeled by using Langmuir equation. And the non-idealities of the systems were corrected by Margules equation. Thus a model with two parameters has been achieved to calculate the interfacial tensions. The comparison of calculating values with the experimental data and the literature data indicates that the model can describe the changes of interfacial tensions following the solute concentrations in good accuracy. |
