| 英文摘要 | A simple and reliable co-electroosmotic capillary electrophoresis system for the fast determination of aromatic acids has been developed by employing poly (1-vinyl-3-butylimidazolium bromide) as the background electrolyte modifier. the polymeric ionic liquid was synthesized by the conventional radical polymerization. the reversed electroosmotic flow was obtained by adding a small amount of the polymeric ionic liquid (0.0006%, w/v) to the electrolyte. to further improve the resolution of aromatic acids, conditions including the concentration of polymeric ionic liquid and ph of background electrolytes were optimized. all eight aromatic acids were baseline resolved in one measurement in a short time (less than 3.5 min) under optimized conditions, 100 mm nah(2)po(4) buffer containing 0.006% (w/v) polymeric ionic liquid, ph 6.0. separation efficiencies were in the range from 355,000 to 943,000 (plates/m). satisfactory reproducibility on the basis of the migration time of analytes was achieved. rsds (n = 3) were less than 0.33% except the p-aminobenzoic acid (0.9%). the applicability of the present method has been demonstrated for the determination of water-soluble aromatic acids in a common drug for external use.
