摘要:

讨论不同有机相与水形成的油/水界面处水/气、油/气及油/水3个界面张力的影响因素及相对大小.重点讨论了加入无机盐对作用于透镜状油滴上的3个界面张力的影响,总结出基本的规律并进行了实验验证.

关键词: 油/水界面, 界面张力, Antonoff规则, Good-Girifalco方程, 无机盐

Abstract:

The properties of the liquid/liquid interface have great effects on the physicochemical processes. In this paper, the influential factors on the relative values of the oil/water, oil/gas and water/gas interfacial tensions and their influence on the shape of an oil drop floating on water surface were discussed. The effect of inorganic salt on the three interfacial tensions was studied to provide guidelines as verified experimentally.

Key words: Oil/Water interface, Interfacial tension, Antonoff rule, Good-Girifalco equation, Inorganic salt
