title: Determination of aniline and its derivatives in environmental water by capillary electrophoresis with on-line concentration.
abstract: This paper describes a simple, sensitive and environmentally benign method for the direct determination of aniline and its derivatives in environmental water samples by capillary zone electrophoresis (CZE) with field-enhanced sample injection. The parameters that influenced the enhancement and separation efficiencies were investigated. Surprisingly, under the optimized conditions, two linear ranges for the calibration plot, 1-50 ng/mL and 50-1000 ng/mL (R > 0.998), were obtained. The detection limit was in the range of 0.29-0.43 ng/mL. To eliminate the effect of the real sample matrix on the stacking efficiency, the standard addition method was applied to the analysis of water samples from local rivers.
