| Capillary Electrophoresis (CE) is an analytical technique in separation sciences and a relative to conventional electrophoresis and chromatography. Since 1981 when Jorgenson and Lukacs improved this technique by a capillary column of 75 mum i.d., CE has been used for the analysis of a wide range of analytes. In this study, this technique was applied to herbicides analysis and charge transfer complexation.;Sulfonylurea (SUs) and imidazolinone (IMIs) herbicides have been widely used in agricultural communities in the past ten years because of low application rates and low mammalian toxicity. Therefore, it is very difficult to build an analytical method to analyze these low use rate herbicides. Several methods have been used for the determination of two classes of herbicides. However, most methods only focus on one individual herbicide or one specific group of herbicides (SUs or IMIs). In this project, capillary zone electrophoresis (CZE) was developed to simultaneously separate twelve active ingredients from SUs and IMIs. The information obtained from this project will be very useful for the future study of these two classes of herbicides using CZE coupled with mass spectrometry (MS). (Abstract shortened by UMI.). |
