Abstract：The content of petroleum pollutants in soil in Yan’an area was determined by gravimetric method and ultraviolet spectrophotometry using trichloromethane and petroleum ether mixed solvent (Vtrichloromethane∶Vpetroleum ether=2∶1) as extractant. Moreover, the extraction of petroleum pollutants in soil and determination method of oil content in soil were compared and studied. The results showed that the extraction results of petroleum pollutants were not satisfactory if single organic solvent was used such as trichloromethane, petroleum ether, dichloromethane, carbon tetrachloride, normal hexane or cyclohexane. When trichloromethane and petroleum ether mixed solvent (Vtrichloromethane∶Vpetroleum ether=2∶1) was used as extractant, the extraction results were good. After extraction, the petroleum pollutants in soil sample were determined by ultraviolet spectrophotometry, with simple operation, a small quantity of reagent and good determination precision. The ultraviolet spectrophotometry was suitable for the determination of petroleum pollutants in soil in Yan’an area.
