| Abstract: | A method for the determination of imidacloprid residue in tobacco leaves by high performance liquid chromatography with solid-phase extraction with DAD detector was established. Tobacco samples were extracted with acetonitrile and cleaned up with a florisil SPE column,then separated in a gradient elution mode.The results showed that the average recoveries of imidacloprid were in the range of 87.83%—94.80%with relative standard deviation of 1.64%,and the limit of detection was 0.01μg/g.The method is sensitive and suitable for the analysis of imidacloprid residue. |
