Chemical fixation of benzyltrimethylammonium groups on vinyl silica surface has been realized using a copolymerization reaction. It has been found that cholic acid is better adsorbed on the modified silica than on choloestyramine. Main paramenters of adsorption - constants of ion exchange, aggregati...
