| 中文摘要: |
| 比较高效液相色谱法和气相色谱-质谱联用法测定植物油中苯并（a）芘含量。结果表明，两种方法均采用中性氧化铝固相萃取柱净化油样，平均回收率均大于75%，相对标准偏差均小于8%，检出限分别为0.12 μg/kg和0.40 μg/kg，均能满足测定要求。相对来说，高效液相色谱法前处理简便，峰形基线平稳，检出限低，回收率高，更适于植物油中苯并（a）芘含量的测定。 |
| 英文摘要: |
| The determinations of benzo(a)pyrene in vegetable oil by high performance liquid chromatography(HPLC) and gas chromatography-mass spectrometry(GC-MS) were compared. The results showed that the commercial neutral alumina solid-phase extraction column was employed to purify oil sample by two methods. The average recovery rates and relative standard deviations of two methods were all above 75% and below 8% respectively, and the limits of detection of two methods were 0.12 μg/kg and 0.40 μg/kg respectively, which could satisfy the measurement requirements. Relatively, HPLC method had the items of simple pretreatment, smooth baseline of peaks, low limit of detection and high recovery rate, which was more suitable for the determination of benzo(a)pyrene content of vegetable oil. |
