Analysis Method of Imidacoloprid Pesticide Residue in Rice

To establish the rapid determination method of imidacloprid residue in rice by high performance liquid chromatograph(HPLC).Imidacloprid residue in rice was extracted with eddy-oscillat method and purified through a florisil column,detected by HPLC at 269 nm.The average recovery rate and RSD were 81.90%-87.80% and 3.24%-4.51% respectively,the detection limits of imidacloprid was 0.001 6 mg/kg.The results showed that the accuracy,precision and sensitivity of the method met the requiremeats of residue analysis of pesticide.
