With quasi-lattice model, surface tension equations for binary solution are derived assuming both mono-and multi-layer surface models. These equations are in agreement with Gibbs adsorption isotherm, and therefore surface relative adsorption can be calculated. The chemical potentials of bulk phase components obtained are also indifferent even if the influence of surface phase is taken into account.
