| Abstract: | A method for the determination of imidacloprid residue in exported vegetables was established by HPLC. The vegetable samples is extracted by acid acetonitrile, cleaned up through a C18 solid-phase extraction column with ethyl acetate, and reversed-phase high performance liquid chromatography with a UV detector. The detection wavelength was 270 nm. The detectable limit of concentration was 0.05 mg/kg. The average spiked recoveries at levels of 0.1 to 0.5 mg/kg were found to be in the range of 86.67% to 100.33% with the relative standard deviations of variation of 3.19% to 9.95%. |
