Determination Method of Organophosphorus Pesticide Residues in Fishs by GPC-GC-PFPD

Abstract:

The 10 organophosphorus pesticides in fish can be rapidly extracted and separated by gel permeation chromatography, and the lipin and organophosphorus pesticides of fish can be seperated. The interfering matters can be well eliminated in this condition, and analysis is more rapid than other methods. The residues of 10 organophosphorus pesticides at same time can be identified and quantified simultaneously by GC-PFPD. This method is simple, rapid, and the average recovery ratios were 71.7%-80.9%.Good repeatability was obtained in all the cases with relative standard deviations (RSDs) lower 11%, and limit of detection was0.0003-0.004 mg·kg^-1.
