摘要：

A study is performed of the adsorption of lysozyme on biporous silica, silicalite-1 (silica with the structure of MFI zeolite), ZSM-5 zeolite, and two halloysite samples (natural aluminosilicate nanotubes). Adsorption isotherms are obtained, and the limiting values of adsorption and the areas on surfaces of the adsorbent per enzyme molecule are found. The maximum adsorption per unit of adsorbent mass (350 mg/g) is obtained for biporous silica along with the one per unit of surface area (0.962 mg/m(2)) on halloysite.
