چکیده مقاله:
We present a theory to predicting surface tension and surface concentration for binary solutions from molar volume, surface tension and bulk concentrations of pure components. The method is applicable to systems comprising components of widely different molecular sizes and the full mole fraction range. We use this theory to binary organic and binary aqueous solutions. Excellent results for the surface tension of binary systems in non-aqueous media have been obtained. The surface tension prediction for aqueous solutions is not as good as for the organic solutions. We also used this theory for predicting adsorption from binary mixture for some aqueous solutions.
