| 中文摘要: |
| 建立了大豆中多环芳烃的快速检测方法。采用乙腈-四氢呋喃（1+1）提取大豆中的多环芳烃，并用高效液相色谱-荧光光谱（HPLC-FLD）法测定多环芳烃含量。方法检出限和定量限分别为0.07～0.61 μg/kg和0.27～2.04 μg/kg，线性范围为2～200 μg/kg，回收率在81.7%～96.5%之间，相对标准偏差在 2.10%～10.44%之间。 |
| 英文摘要: |
| A rapid method for detecting polycyclic aromatic hydrocarbons (PAHs) in soybean was developed. After the soybean was treated with acetonitrile-tetrahydrofuran (1∶1), the PAHs contents were determined by HPLC-FLD. The detection limit and the limit of quantification of the method were 0.07-0.61 μg/kg and 0.27-2.04 μg/kg, respectively. For the twelve PAHs, the method had a good linear range, which was 2-200 μg/kg. The recovery rate ranged from 81.7% to 96.5% and the relative standard deviation was in the range of 2.10%-10.44%. |
