| 中文摘要: |
| 采用气相色谱法测定油田区土壤中C10～C40的石油烃，通过优化加速溶剂萃取的条件，使方法在62 mg/L～3 100 mg/L范围内线性良好，方法检出限为48 mg/kg。用该方法测定石油区短期、中期、长期油井污染土壤样品，5次测定结果的RSD为13%～52%，加标回收率为848%～985%，有证标准样品测定结果在可信区间内 |
| 英文摘要: |
| Petroleum hydrocarbon of C10～C40 in oilfield soil was determined by gas chromatography. By optimizing the conditions of accelerated solvent extraction，the method had good linearity in the range of 62 mg/L~3 100 mg/L，the detection limits were 4.8 mg/kg. Applying the method to short term, medium term and long term contaminated oilfield soil，the RSDs of five repeated measurements were 1.3%~5.2%，the recoveries were 84.8%~98.5%，the determination result of certified reference material was within the confidence interval. |
