Abstract:A quantitative gas chromatographic method adopting FID and HP-5 capillary column has been developed for the determination of the diflufenican TC. The assay exhibited a good linearity in diflufenican concentration range from 0.41 to 51.5 μg/mL,with correlation coefficient of 0.999 98. The variation coefficient and average recovery were 0.14% and 99.74%,respectively.
Key words:diflufenican;herbicide;capillary gas chromatography
