Abstract
A method has been proposed for the determination of 17 herbicides and their metabolites in natural waters by capillary zone electrophoresis with UV detection at 190 nm. Dispersive liquid-liquid microextraction with trichloromethane has been used for pesticide recovery from water. The high sensitivity of determination has been provided by additional intracappilary preconcentration: the limits of pesticide detection in water involving off- and on-line preconcentration are 0.5–3.0 μg/L. The analysis takes 1–1.5 h; the relative standard deviation of the analysis results does not exceed 5%.
