Concentration fluctuations and surface adsorption in non-ideal binary mixtures. A light-scattering and surface tension study
Abstract
The concentration fluctuations and the surface tension of binary mixtures of non-electrolytes have been measured at 298.15 K, using light scattering and plate
The experimental results have been compared with the predictions of several solution models that have been recently used for predicting Γ12 from surface tension data. It has been found that, in spite of being used in many recent papers, the UNIFAC model leads to rather poor predictions. The experimental results have also been compared with the predictions of a lattice-fluid model, the agreement is not satisfactory.
