Surface tension prediction of binary mixtures by using scaled particle theory coupled with one fluid theory

The surface of a liquid has interesting properties which appear as the surface tension. The surface tension play an important role in chemical industry, biological membranes operation, electrochemical reactions, mass transfer such as distillation, adsorption, extraction and several other processes [۱].There are a lot of methods to predict the surface tension of binary mixtures including Escobedo and Mansoori, Miller andFainerman,Ramkrishnaand…, but these methods required more information and data about structure, density, critical temperature and pressure, molar volume and some other properties. So, in this paper we present a very simple model to predict surface tension of binary mixtures. This model gives useful information such as hard sphere diameter.
