| Abstract: | The pretreatment methods of NY/T 761 - 2008 for detecting pesticide residues chlorpyrifos in vegetable have been optimized. At the same time GC - FPD detection method was built. The results showed that the recovery of the optimized GC - FPD detection method ranged between 80.5% -95.5%, detection limits reached 0. 01 mg/kg, the relative standard deviation ranged between 2.5% -7.2%. The optimized pretreatment method has good result and the new detection method built is accurate, and easy to operate. |
