Equilibrium of α-tocopherol and β-sitosterol adsorption onto MCM-41 and organic-inorganic composites
Abstract
The equilibrium of α-tocopherol and β-sitosterol adsorption from hexane solution onto parent
MCM-41 and aminosilane (MN) and chlorotrimethylsilane (MC1) composites has been studied. It is shown
that grafting allows to save high ordered structure with high specific area, large pore volume and narrow pore
size distribution of MCM-41. The distribution coefficients of these biological active substances between
solution and the sorbent phase are calculated. A significant influence of the interactions sorbate-sorbate,
sorbate-sorbent, sorbate-solvent interactions is established.
