Linear solvation energy relationships based on application of the Kamlet-Taft model were used to predict the interfacial tension and surface excess isotherms, the surface excess at saturation, and the free energy of adsorption for the model hydroxyoximes of various hydrophobicity in systems containing octane, toluene, and their mixtures as model diluents. The obtained relationships are accurate enough for such estimation and, except for the equation for the free energy of adsorption, they do not depend on hydroxyoxime hydrophobicity.
