摘要：

Using high-performance liquid chromatography under conditions close to equilibrium, adsorption has been investigated for a series of aromatic compounds from water-acetonitrile, water-methanol, and water-isopropyl alcohol solutions on hyper-cross-linked polystyrene with the degree of cross linking of 500%. The principles of the effect of the nature of binary water-organic solvents on thermodynamic characteristics of adsorption of the studied substances on hyper-cross-linked polystyrene have been determined. The role of intermolecular interactions, which are realized in bulk solution and interface, in the adsorption of aromatic compounds from their maximum diluted water-organic solutions on hyper-cross-linked polystyrene has been discussed. The compensation effect upon adsorption on hyper-cross-linked polystyrene individually from water-acetonitrile solution and various water-alcohol solutions has been discovered. The existence of linear dependences between the differences of Gibbs energy upon adsorption from water-organic solutions on hyper-cross-linked polystyrene has been shown.
