The adsorption and chromatographic properties of modified silica sorbents for application to different viruses have been investigated. Minimal adsorption of viruses was observed on macroporous silicas with hydrophilic properties of the sorbent surface. The universal sorbent for the gel-permeation ch
Activated carbon fibers (ACFs) have relatively uniform slit-shaped micropores. A silica film was deposited on the micropore walls by adsorption of SiCl, on the micropores, then successive reaction of adsorbed SiCl, with H,O, and heat treatment using a greaseless vacuum line. The silica-modified ACF
