Herbicide analysis by micellar electrokinetic capillary chromatography

摘要: Capillary electrophoresis with ultraviolet detection (CE-UV) and laser-induced fluorescence (CE-LIF) was used for analysis of a group herbicides that have widespread use in the USA. CE-UV employed simultaneous determination atrazine, simazine, alachlor metolachlor water. In addition, also suitable dicamba, 2,4-D chlorimuron ethyl. Dicamba, ethyl were analyzed using CE-LIF following derivatization fluorescent reagents. Dicamba derivatized 4-bromomethyl-7-methoxycoumarin dansyl chloride hydrolysis. The limit simazine 0.1 μg/l 1.0 μg/l. estimated 10 ng/l. Our results demonstrate CE provides powerful new analytical tool herbicide analysis.
