| 中文摘要: |
| 采用SPE固相萃取柱净化，利用气质联用仪以外标法定量检测玉米油中16种多环芳烃（PAHs）。结果表明：经NIST谱库检索，能够确认16种PAHs，并能检测其在玉米油中的质量浓度。样品加标回收率检测中，加标量1 μg/L时，16种PAHs回收率为74.6%～89.8%，RSD为4.6%～9.2%；加标量10 μg/L时，16种PAHs回收率为82.3%～97.9%，RSD为4.8%～9.8%。 |
| 英文摘要: |
| After the purification of SPE solid-phase extraction column, 16 kinds of polycyclic aromatic hydrocarbons (PAHs) in the corn oil were quantitatively detected by GC-MS using external standard method. The results showed that by the NIST spectrum library retrieval, 16 kinds of PAHs were confirmed, and their mass concentrations in corn oil were detected. In the sample standard addition recovery test, recovery rates of 16 kinds of PAHs reached 74.6%-89.8% and RSD were 4.6%-9.2% with 1 μg/L of standard addition, and recovery rates of 16 kinds of PAHs reached 82.3%-97.9% and RSD were 4.8%-9.8% with 10 μg/L of standard addition. |
