| Abstract: | A liquid chromatography-tandem mass spectrometric(LC-MS/MS) method was established for the determination of tebufenozide,aldicarb,aldicarb-sulfoxide and aldicarb-sulfone in scallion.The samples were extracted with acetonitrile and ethyl acetate,respectively.It was found that the extraction efficiencies of 4 pesticides with acetonitrile were better than those with ethyl acetate.Co-extractives were removed from the acetonitrile extracts using dispersive solid phase extraction(DSPE).The calibration curves were... |
