Abstract
The maximum adsorption capacity of bovine brain galactocerebroside on samples of silicalite-1 synthesized on solid supports (in powder form and applied to glass) is determined. It changes in the range of 6 to 27 mg/g, depending on the accessibility of adsorbent pores for lipid molecules. IR spectroscopy data show that the lipid molecules are oriented with carbohydrate fragments facing the adsorbent surface. It is established that adsorption of protein molecules (BSA and hemoglobin) occurs predominantly on the lipid, and only partially on the free outer surface of the silicalite. It is concluded that adsorption alters the parameters of the porous structure.
