Popis: The paper presents the method of preparation and determination of physicochemical properties of silica gels with a chemically bonded BSA phase as well as studies of the effect of support porosity on the synthesis. Wide-porous Z-300 and narrow-porous Z-100 silica gels were studied. The investigations showed a significant effect of pore size on the synthesis of stationary phases with BSA. Modification with protein results in changes of adsorption properties and porosity of adsorbent samples. Changes of physicochemical properties result in significant changes of geometrical and structural heterogeneity of the support (specific surface area, fractal coefficient) as well as energetic heterogeneity of the samples.
