英文摘要	A rapid and sensitive method for the detection of acidic herbicides in soil was developed by in-situ derivatization complexing extraction with Na-4-EDTA as complexing reagent and pentafluorobenzyl bromide (PFBBr) as derivatization reagent combining with GC-negative ion chemical ionization (NCI)-MS. On the basis of sufficient mixture of 10. 0 g soil, 1.5 mL H2O, and 0.5 g Na-4-EDTA, the derivatization and extraction was completed in 10 min, with elevated temperature (100 degrees C) and pressure (10.3 MPa) by accelerated solvent extractor (ASE) with excessive PFBBr in the extraction cell. The extract was detected after drying and clean-up. The correlation coefficient (r(2)) > 0.990 in the samples concentration of 10-500 mu g/kg, the MDL was 0.8-7.7 mu g/kg, the recovery was 70%-130%, and the RSD was 2.0%-8.0%.
