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4.8 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1.3%~5.2%,加标回收率为84.8%~98.5%,有证标准样品测定结果在可信区间内。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.
