摘  要：
[Aims]The ultra-high performance liquid chromatography-tandem mass spectrometric(UPLC-MS/MS)method was developed for the simultaneous determination of seventeen pesticide residues in vegetables.[Methods]The samples were extracted and cleaned up by matrix solid-phase dispersion extraction,separated by UPLC and detected by mass spectrometry detector.[Results]The correlation coefficients were between 0.999 5 and 0.999 9 with the linear range of0.005-0.5 mg/L.The limit of detection were 0.001-0.004 mg/L.When the spiked levels were between 0.025 and 0.5 mg/kg,the average recoveries of seventeen pesticides in vegetables ranged from 73.44 to 101.58%and the relative standard deviations were between 0.73 and 11.09%.[Conclusions]The method is simple,precise,cheap,high sensitivity and selectivity,which fits the determination needed for the multi residue pesticides in vegetables.
