摘　　要：A mode of capillary electrochromatography(CEC) based on the dynamical adsorption of an nonpolar monolithic stationary phases with a cationic surfactant, long chain quaternary ammonium slat of cetyltrimethylammonium bromide(CTAB) has been developed. The effects of pH value and the concentration of cetyltrimethylammonium bromide in mobile phase on electroosmotic mobility and the retention factors of solutes were investigated.A mode of capillary electrochromatography(CEC) based on the dynamical adsorption of an nonpolar monolithic stationary phases with a cationic surfactant, long chain quaternary ammonium slat of cetyltrimethylammonium bromide(CTAB) has been developed.
