Determination of seven amide herbicides in soil by accelerated solvent extraction combined with GC-MS
An accelerated solvent extraction-gas chromatography-mass spectrometry method was established for the determination of seven amide herbicides in soil:acetochlor,ipropachlor,meachlor,ipropachlor,dicarboxylate,butachlor and propachlor.The linearity of the seven amide herbicides was good in the concentration range of 3.00～200µg·L-1,and the detection limits were 0.007～0.013mg·kg-1.The recoveries of the seven amide herbicides spiked at three concentrations were in the range of 87.9％～104.2％,the RSDs were in the range of 1.87％～4.38％(n=6).This method is simple,sensitive,accurate and precise,which is suitable for the analysis of amide herbicide residues in soil.
