Atrazine and simazine determination in river water samples by micellar electrokinetic capillary chromatography

Abstract
A rapid and sensitive micellar electrokinetic capillary chromatography analytical method was used for the determination of chlorotriazine herbicides in river water samples. Several electrolyte systems in the pH range 7–10 were tested in order to optimize the separation. The two compounds were separated in less than 10 min and the determination limit was about 0.4 ppb for each herbicide. Recovery values of the method were in the range 80%–117%.
