High-performance liquid chromatog. is used under near-equilibrium conditions to study the adsorption of isomeric dipyridyls and their derivatives from water-acetonitrile, water-methanol, and water-isopropanol solutions onto Hypercarb graphite-like carbon material in the region of Henry’s law. It is shown that the possibility of forming strong intramol. C-H-N’-hydrogen bonds in a mol. of 2,2′-dipyridyl or its derivatives strengthens the adsorption bonding of adsorbate mols. and the surface of the graphite-like material due to stabilization of their planar conformation. Destabilizing this intramol. hydrogen bond by adding substituents in different positions of the pyridine rings enhances the specific intermol. interaction between adsorbate mols. and the solvent’s components and distorts the planar conformation of dipyridyls, weakening their retention on the Hypercarb material. Pos. adsorption from the water-organic medium on the carbon adsorbent is observed for all of the investigated dipyridyls, with the exception of 2,2′-dipyridyl-N,N’-dioxide, which is adsorbed weaker than the solvent components. Anomalous medium-property dependences are found for the thermodn. characteristics of the adsorption of dipyridyls on porous graphitic carbon, and are attributed to the predominance of adsorbate-adsorbent π-π interactions over hydrophobic ones and the resolvation of adsorbate mols. with acetonitrile in proportion to lowering the content of water in the bulk solution
