| Abstract: | A simple and sensitive capillary zone electrophoresis method has been established to determine acetic acid and chloroacetic acid in water by using potassium hydrogen phthalate(pH = 5.4) as the background electrolyte,hexadecyltrimethylammonium bromide as electroosmotic flowing inhibitor,and methyl tert-butyl ether as the extractant to treat water sample.It was found that acetic acid and chloroacetic acid in water could be determined with relative standard deviation of migration time and corrected peak area b... |
