| 英文摘要 | a novel monolithic silica column with zwitterionic stationary phase was prepared by in-situ covalent attachment of phenylalanine to a 3-glycidoxypropyltriethoxysilane-modified silica monolith. due to the zwitterionic nature of the resulting stationary phase, the density and sign of the net surface charge, and accordingly the direction and magnitude of electroosmotic flow in this column during capillary electrochromatography could be manipulated by adjusting the ph values of the mobile phase. cec separations of various acidic and basic compounds were performed on the prepared column in anodic and weakly cathodic eof modes, respectively. the peak tailing of basic compounds in cec on a silica column could be alleviated at optimized buffer compositions. besides the electrophoretic mechanism and weak hydrophobic interaction, weak cation- and anion-exchange interactions are also involved in the separations of acids and bases, respectively, on the zwitterionic column. |
