Determ ined the Lyophobicity for Binary Mixture with Extended Langmuir Model

The surf ace tension for the inves tigation of the molecul ar interactio ns in liquid mixture is t he better th an other exp erimental m ethods bec ause this thermodynamic property is also easy to measure and usually presents a very strong dependence on both, the compounds constitutin g the mixt ure and their relative concentrations . The surface tension of mixture is an important physical property in mass transfer processes such as liquid-liquid extraction, g as absorption,distillatio n and condensation [۱ ]. In this paper by using literature surface ten sion data for binary m ixture, the surface mole fraction (xBS ) and the lyophobicity (β) were derived usin g the exten ded Langmuir model at different t emperature. The value o f (β) is di scussed bas ed on interaction forces.
