| Abstract: | A new analytical procedure based on matrix solid-phase dispersion(MSPD)combined to gas chromatography with mass spectrometric detection were developed for the determination of 80 pesticides in vegetables.The sample,which required Florisil as dispersant sorbent,graphitized carbon black as purificant and ethyl acetate as eluting solvent,was determined by GC-MS with selected ion monitoring.The result showed that recoveries of 80 pesticides ranged from 63.7%～117.8%,and relative standard deviations were below 18%.The limits of detection for the method were from 3.5～10.8μg/kg. |
