چكيده فارسي :
Surface tension of aqueous binary solutions of alcohols have been correlated as a function of composition using the Li et al. (LWW) model by new method at various temperatures(293.15-323.15) K. The surface tension data over the entire concentration range are correlated by this method, then the interaction energy between two compounds of mixtures and their coefficient activities have been calculated with the results of this model based on Wilson equation. Also, the UNIFAC group contribution model is applied for calculation of activity coefficients of components in solution. The obtained results by this new method show that the good agreement between theory and experiment.
