Abstract

Highly dispersed silica samples with different degrees of substitution of silanol groups by trimethylsilyl groups are obtained by the gas-phase modification method. The adsorption of vitamins B1, B6, and E on initial and modified silica samples is studied. It is shown that the modified adsorbents with degrees of substitution of silanol groups up to 40% exhibit higher affinity to vitamin molecules; in this case, adsorption properties of the modified silica samples depend on the nature of the adsorbate and the number of grafted groups.
