| Abstract: | Systematically studied the residues of flusilazole in apple and soil to promote the safety production.Methods] Samples were extracted by acetonitrile,purified by adsorption dispersant PSA,and determined by HPLC-UV.Results] The detectable limit of this method was 9.9×10-3 mg/kg,the average recovery rate was 71.5-105.0%,the relative standard deviation was 2.4-8.2%.Conclusions] The method was fast,simple and sensitive with good accuracy. |
