| Abstract: | The captan residue was extracted from grape samples by the mixture of acetone and ethyl acetate with the volume ratio of 1 ︰ 1 after being homogenized.The extracts were purified by florisil,then detected by GC with ECD-detector.The minimum detectable amount of captan was 0.5 × 10-12 g,the minimum detectable concentration in plants,soil and grains was 0.01 mg/kg,the average recovery rate ranged from 94.0% to 95.3% with the relative standard deviation of 2.6% ～ 7.3%,which accorded with the demands of residue analysis. |
