| Abstract: | The capillary electrophoresis analysis of anions in photodegradation products of imi-dacloprid was studied. The background electrolyte consisted of chromate and myristyltrimethylammonium bromide. Indirect UV detection at 254nm was used. In selected conditions, various anions (Cl-, NO2-, NO3) in this system were separated within 3 minutes, and the relative standard deviation of migration time and peak area was less than 1% and 5% respectively (n = 9). Results showed that the concentrations of Cl- and NO3- in photodegradation product increased with prolonging exposure to the light and tended to constant. |
