Predicting adsorption coefficients at air-water interfaces using universal solvation and surface area models

Different models for predicting partioning between the vapor phase and the macroscopic surface of liquid water was discussed. The first model called SM5.0R-Surf, involved atomic surface tensions developed for bulk solvation in organic liquids. The second model was found to be empirical correlation of the interfacial-water partition coefficient with the van der waals surface area. The new SM5.0R-Surf model was expected to predict the free energy of the solvation at air-water interfaces and in bulk organic liquids for any solute.
