Studies on adsorptive properties of porous copolymers for HPLC

The adsorptive properties of four porous copolymers were investigated. They contained different functional groups in the internal structure. Adsorption measurements were made using the static method. Three two-component and one three-component solutions with different physicochemical properties were used. The adsorptive centers of the copolymers were evaluated based on the analysis of excess adsorption isotherms of the polar solution component.
