Fortified water samples were extracted by solvent partitioning with methylene chloride and analysis by CE. Fortified soil samples were extracted by shaking in methanol–phosphate buffer (1:1) followed by partitioning of the residues into methylene chloride and analysis by CE. The method was simple, rapid and yielded excellent recoveries. Average recoveries were greater than 90% for both herbicides fortified at 10 μg/l in lakewater samples and at 50 μg/kg in soil samples. Our results demonstrate that capillary electrophoresis provides a powerful analytical tool for determination of the residues of primisulfuron and triasulfuron in water and soil samples.}, number={1-2}, journal={JOURNAL OF CHROMATOGRAPHY A}, author={Penmetsa, KV and Leidy, RB and Shea, D}, year={1997}, month={Apr}, pages={225–231} }

Commercially available cyclodextrins were evaluated for separation of the enantiomers and isomers of the three herbicides having varied molecular structures. The enantiomers of imazaquin and diclofop, and the isomers of imazamethabenz could be resolved with a resolution of ≥1.5. The resolution was found to depend on pH of the run buffer, cyclodextrin type and cyclodextrin concentration. By employing mixed cyclodextrins in the running buffer, the three herbicides were simultaneously separated in a single run. In addition, rapid (less than 3 min) enantiomeric separation is demonstrated using imazaquin as a model herbicide. The reported capillary electrophoresis (CE) methods are simple, rapid, efficient and reproducible and our results demonstrate that CE provides a powerful analytical tool for enantiomeric and isomeric separation of herbicides.}, number={1-2}, journal={JOURNAL OF CHROMATOGRAPHY A}, author={Penmetsa, KV and Leidy, RB and Shea, D}, year={1997}, month={Nov}, pages={225–234} }
