Determination of metoxuron and 3-chloro-4-methoxyaniline via direct derivatization with heptafluorobutyric anhydride and GC-ECD

Add time:09/07/2019    Source:sciencedirect.com

The phenylurea herbicide metoxuron and its main metabolite, 3-chloro-4-methoxyaniline, can be determined rapidly in aqueous samples via extraction, derivatization with heptafluorobutyric anhydride (HFBA), washing with an aqueous bufferof pH 8, and analysis by capillary GC with electron capture detection. Linear calibration curves are obtained over two orders of magnitude, and the detection limit for the HFB derivatives is about 0.5 pg. The method has successfully been applied to several types of water samples.
