【Abstract】 Six nitrophenolic compounds were extracted from the soil by accelerated solvent extraction apparatus. The extraction conditions were determined by screening and optimizing the solvent type, extraction temperature and extraction times. After purification, the extraction liquid was detected by gas chromatography-hydrogen flame ionization detector and quantified by external standard method. The results show that the method is stable and accurate in detecting six nitrophenol compounds in soil.更多还原
