| 中文摘要: |
| 采用ASE萃取-弗罗里硅土净化-HPLC法和ASE萃取-GPC净化-HPLC法测定土壤中苯并(a)芘，并将2种方法的测定结果作比对。试验表明，方法在0.02 mg/L～0.500 mg/L之间线性良好，当取样量为10 g时，弗罗里硅土净化土壤样品方法检出限为8.93×10-5 mg/kg，平均加标回收率为72.7%～73.8%，3次测定结果的RSD为4.0%～4.5%；凝胶色谱净化土壤样品方法检出限为1.98×10-5 mg/kg，平均加标回收率为88.8%～90.2%，3次测定结果的RSD为 2.1%～2.8% |
| 英文摘要: |
| Two methods have been established and compared for determining Benzo(a)pyrene (BaP) in soil by ASE(accelerated solvent extraction) Florisil purification HPLC detection and ASE GPC(gel purification chromatography) purification HPLC detection. Good linearity was observed when BaP concentrations were between 0.02 mg/L and 0.500 mg/L. When sampling amount was 10 g, the detection limit of florisil purification was 8.93×10-5 mg/kg, the average spiked recoveries were between 72.7% and 73.8%, the relative standard deviations were 4.0%～4.5%. The detection limit of GPC purification was 1.98×10-5 mg/kg，the average spiked recoveries were between 88.8% and 90.2%, the relative standard deviations were 2.1%～2.8%. |
