| A method was developed for the determination of 15 triazole pesticides in vegetables and fruits by gas chromatography(GC) and gas chromatography-mass spectrometry(GC-MS) with ion exchange column.The samples were pretreated quickly,then extracted with acetonitrile after sodium chloride homogenization，separated by liquid-liquid partition．The clear supernatant purified by solid phase extraction with ion exchange column was ready for GC-ECD and GC-MS analysis．Determinations were performed by using selected ion monitoring(SIM) mode,and external standard method was used for quantification．After optimizing the conditions for pretreatment and determination，the method was convenient and rapid．Under the optimal conditions,the quantitation limits of the method(S/N≥10) were 0.01 mg/kg.The recoveries at spiked levels of 0.01，0.05,0.10 mg/kg were in the range of 68%-102% with the relative standard deviations of 2.4%-16.2%.Besides,the pretreatment has a good purification effect in GC-ECD chromatogram.The method is easy，rapid and sensitive,and could meet the requirements for the analysis of 15 triazole pesticides in vegetables and fruits. |
