摘要:

文章建立了应用HPLC-MS/MS快速测定蜂蜜中五氯酚残留的分析方法。样品经氨化乙酸乙酯(9∶1,VV)涡旋超声提取,提取液经氮气吹干,液相色谱串联质谱测定,内标法定量。在五氯酚添加浓度为0.5、2.0、10.0 μg·kg-1时,回收率为93.5%~101.3%,相对标准偏差(RSD)为4.30%~6.82%,其检出限和定量限分别为0.2 μg·kg-1和0.5 μg·kg-1。结果表明,此方法操作简单快捷、灵敏度高、重复性好、环保可靠,完全适用于蜂蜜中五氯酚残留量的测定。

Abstract:

A method for rapid determination of pentachlorophenol residues in honey by HPLC-MS/MS was established. The sample was extracted by ammoniated ethyl acetate (9∶1, VV), concentrated and determined by liquid chromatography tandem mass spectrometry, and quantified by internal standard method. Under the optimal conditions, the recovery ranged from 93.5% to 101.3% at the three spiked levels (0.5, 2.0 and 10.0 μg·kg-1) and the relative standard deviations ranged from 4.30% to 6.82%. The limits of detection and quantification were 0.2 and 0.5 μg·kg-1, respectively. This method is simple, fast, and reliable, and can be used to determine pentachlorophenol residues in honey.
