Abstract
The chromatographic retention and thermodynamic characteristics of adsorption of several derivatives of 2-arylpropanoic acid on a chiral stationary phase with a grafted eremomycin antibiotic under the conditions of liquid chromatography with water-ethanol mobile phases were studied. The dependences of retention characteristics and selectivity on eluent pH were revealed. The difference between the adsorption mechanisms of acids with one and two benzene rings was demonstrated. Compensation effect manifestations in these systems are discussed.
