Abstract
A method for the simultaneous determination of 10 fungicides residues in vegetables by gas chromatography- mass spectrometer (GC-MS/MS) was established. The samples were extracted by ethyl acetate cyclohexane, and the aminosolid phase extraction column purification was preferred. Which were detected by multi-reaction monitoring (MRM), and quantified by external standard method. The results showed that the linear relationship of 10 fungicides in the mass concentration range of 15~500 ng/mL was good, and the correlation coefficient was all greater than 0.999 1, with the detection limit of 0.1~0.5 μg/kg. The actual recoveries of the samples were 84.7%~117.0%, and the relative standard deviation (n=6) was 0.4%~4.7%. This method is suitable for the simultaneous detection of a variety of fungicides in vegetables.
