This study develops a model to fit the surface tension of the water/ethanol mixture for the complete composition range from 0 to 1. The theoretical framework complements Van Der Waals theory on the density gradient. The modelling results overcome the limitation of Gibbs adsorption isotherm, which completely ignores the composition of the interfacial layer. Furthermore, the model presents a new method to correctly calculate the composition of the interfacial layer for binary liquid mixture and surfactant solutions.

水/乙醇混合物的表面张力和界面组成

本研究开发了一个模型来拟合水/乙醇混合物的表面张力,以适应从 0 到 1 的完整组成范围。该理论框架补充了关于密度梯度的范德华理论。建模结果克服了吉布斯吸附等温线的局限性,完全忽略了界面层的组成。此外,该模型提出了一种新方法,可以正确计算二元液体混合物和表面活性剂溶液的界面层组成。
