Abstract

This paper established a multi-residue detection method of amides, neonicotinoids, triazoles, heterocyclic, and other pesticides in fruits and vegetables samples by liquid chromatography - tandem mass spectrometry. Using QuEChERS as sample pretreatment method, then extracted by acetonitrile, cleaned up by graphitized carbon black using dispersed solid phase extraction. After the separation of chromatographic column, the extraction was analyzed under the LC-MS/ MS multiple reaction monitoring mode. Ten kind of pesticides detection is limited between 0.006 ~ 0.133 g/kg, and the quantitative is limited between 0.018 ~ 0.415 g/kg. On the three adding levels between 1~10 g/kg, the average recovery is 76.2 % ~ 96.3 %, RSD is less than 2.4 %. This method can be used in the pesticides multi-residue detection of fruits and vegetables samples.
