Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. screened out two environmentally friendly extractants for the determination of petroleum hydrocarbons (C10-C40) in soil by gas chromatography. Using n-hexane-ethanol (3:1) as the extraction solvent , the extraction rate of petroleum hydrocarbon was 90.47%, which met the analysis requirements. The linear correlation coefficient of the standard working curve was 0.9993, the detection limit of the method was 3.36 mg/kg, and the recovery rate of standard addition was 78.23 in the range of 15.5-620 mg/kg. %～90.45%, the relative standard deviation is 2.03%～6.72% (n=6). Compared with the commonly used extractants, this extractant is more economical and environmentally friendly.
