- Objective to established a gas chromatography mass spectrometry method for the determination of the 8 phosphorus and carbamates pesticide residues in organic vegetables. The vegetable sample was homogenate, after the extraction of acetonitrile. The detection of the GC/MS was carried out by solid phase extraction column. The mass spectra of 8 kinds of organic phosphorus and organic amino acid esters of formic acid esters are effective, the detection limit was 0.003~0.008mg/kg. The average recoveries of the 8 pesticides were from 74.7% to 93.2% in the range of 0.025~1 mg/kg. The relative standard deviation was from 8.08% to 9.17%. This method is simple for sample treatment, with a good purifying effect and ease popularization, and it can provide a method for the determination of organic phosphorus and pesticide residues in vegetables.
