摘要
Laws governing the sorption of quinoline derivatives on hypercrosslinked polystyrene are studied under conditions of reverse-phase high-performance liquid chromatography. Factors of sorbate retention at different concentrations of acetonitrile in the eluent are determined. An analysis is performed of the dependences of variation in the enthalpy of sorption and the entropy term of the temperature dependence of the retention factor on the content of the organic component in the eluent for the studied compounds.
