Abstract: |
Using QuEChERS rapid purification column to pretreat sample, the procymidone and flusilazole pesticides residues in vegetable oil were determined by GC-MS. The results showed that the recoveries of procymidone and flusilazole were 85.0%-96.0% and 88.3%-94.1%, respectively; the intra-laboratory variation coefficients of procymidone and flusilazole were 1.5%-8.9% and 2.1%-68%, respectively; the detection limits of procymidone and flusilazole were 0.007 5 mg/kg and 0.022 5 mg/kg, respectively. The method had the advantages of simple pretreatment, high sensitivity and good reproducibility. |
