Adsorption of cholic acid on silica modified with benzyltrimethylammonium groups
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...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | 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, aggregation, and stability - have been calculated, and conclusion about mechanism of cholic acid adsorption on modified silica have been made. |
