【Abstract】 Four compounds of p _ chloroaniline, p _ bromoaniline, 2,4 _ dichloroaniline and p _ iodoaniline were separated by micellar electrokinetic capillary chromatography(MECC). The chromatographic conditions were studied. Under the selected experimental conditions, the RSD of migration time of aniline derivatives was less than 0.5% and that of peak area was less than 3.0%. The detection limits were 1.2×10-6～4.2×10-6 mol/L. The results of waste water analysis from a lab were satisfied.更多还原
