| Abstract: | Methods] A method was studied to determine the residue of propiconazole in soybean.Residues of propiconazole were extracted from samples with acetonitrile,cleaned up on Florisil column,determined with GC-ECD.Results] The minimum determination concentration was 0.02 mg/kg,the average recovery rate was 85.5-108.2%,the relative standard deviation was 4.9-18.4%.Conclusions] The method was fast,simple and sensitive with good accuracy. |
