Abstract

The kinetics of the adsorption of lysozyme and bovine serum albumin (BSA) onto zeolites of BEA and MFI structural types and onto silica adsorbents of the same structural types was studied. The rate constants of the reversible adsorption step were calculated. The adsorption rate constants are 0.4–0.8 L mol^–1 s^–1 for lysozyme and 0.7–1.4 L mol^–1 s^–1 for BSA. The rate constants of the desorption from the surface of all the samples are in the range from 1.3 × 10^–5 to 1.6 × 10^–5 s^–1 for both enzymes.
