Abstract Cyclodextrin-modified micellar electrokinetic chromatography was applied successfully to the enantiomeric and isomeric separation of 7 commonly used pesticides (propiconazole, bioallethrin, fenpropathrin, phenothrin, bitertanol, triadimenol, and dimethomorph). Commercially available surfactants used alone or in combination with cyclodextrins were evaluated for separation of the enantiomers/isomers of the 7 pesticides. The enan-tiomers/isomers of the pesticides used in this study were baseline resolved with resolutions of ≥1.5. The resolution was found to depend on the type of surfactant and cyclodextrin employed in the running buffer. In the case of propiconazole and dimethomorph, baseline resolution was also achieved by adding sodium cholate (a chiral surfactant) alone to the running buffer. Analysis of fortified water samples yielded recoveries ranging from 45 to 89% and method detection limits ranging from 0.18 to 2.1 ppb. The reported capillary electrophoresis methods are simple, rapid, and reproducible.
