摘  要:
The matrix effects of 14 organophosphorus pesticides in 9 kinds of vegetables matrices were preliminarily studied by gas chromatography /flame photometric detection( FPD) in the paper. The matrix effects of 14 organophosphorus pesticides in 9 kinds of vegetable matrices at 0. 05,0. 1 and 0. 2 mg / L were compared,respectively. The results showed that matrix enhancement effect and matrix attenuation effect existed in all cases,while matrix effects did not have strong correlation with concentrations of pesticides,but were related to species of vegetables and structure and polarity of pesticides.
