| Abstract: | Using the thermodynamic consistency of adsorption for vapor or liquid phase together with the consideration of solution theory,surface thermodynamics and phase exchange model, the model for prediction of adsorption equilibria from binary solutions on solids with the adsorption isotherm of pure unsaturated vapors was proposed.The model only has four unknown parameters.Binary systems were tested with the proposed method.The results show that the predictive values have a good quantitative agreement with the experimental data. |
