| Abstract: | Objective]To established the pretreatment method for determining pesticide residues in food with gas chromatography. Methods]The samples were distilled by Florisil columns, separated by capillary gas chromatography, and then detected by NPD and ECD.Results]The recovery of pesticides ranged from 71.2%to 115%, the relative standard derivation （RSD） was 2.5%~12.4%.Conclusion]This method is of complete extraction, quite purification , accuracy, simplicity, which can meet the needs of multi-pesticide residues determination. |
