The purpose of this study was to optimize the pre-treatment process for the detection of 9 organophosphorus pesticide residues in cabbage by gas chromatography, and to conduct a comparative experiment between this method and the standard method NY/T 761-2008 of the Ministry of Agriculture. The results show that the optimized pre-treatment method is to use 10 mL acetonitrile as the extractant, 150 mg N-propyl ethylenediamine (PSA) and 15 mg graphitized carbon black (GCB) as the purification agent, which can reduce the use of extractant and inorganic salt in the pre-treatment process, increase the recovery and detection limit, reduce the matrix effect and cost of instrument maintenance.
