Abstract

HCl are studied. It is found that monolayer binding of vitamin E in the structural matrix of the
adsorbent is determined by the formation of hydrogen bonds the silanol groups of the adsorbent with
oxygen atoms ring and phenolic radicals of vitamin E. The polymolecular nature of adsorption is caused
by solvophobic interactions with the formation of adsorbate associates. The equilibrium characteristics of
adsorption are evaluated
