QuEChERS-GC/MS快速检测柑橘中50种农药残留
Rapid Determination of 50 Pesticide Residues in Citrus by QuEChERS-Gas Chromatography-Mass Spectrometry
摘要
Abstract
An analytical method for the rapid determination of 50 pesticides residues in citrus by gas chromatography-mass spectrometry(GC-MS) with QuEChERS was established in a selected ion-monitoring(SIM) mode.The pesticide residues in samples were extracted into acetonitrile and salted out by anhydrous MgSO4 and NaCl.Then,the pesticide residues in the supernatant after clean-up on N-propyl ethylenediamine(PSA) cartridge were subjected to GC-MS analysis.Under the optimal conditions,the limits of detection(RSN = 3) of the established method were in the range of 0.0038-0.066 mg/kg,and the average recovery rates(n=6) for 50 pesticide residues in a blank sample were 72.0%-118.2% with a relative standard deviations(RSDs) of 1.7%-19.7%.关键词
