| 摘 要： | 提出了一种用于测定主流烟气中痕量苯并 a]芘的方法。以甲醇 正庚烷萃取体系初步处理主流烟气中的总粒相物 (TPM) ,接着以KOH甲醇溶液数毫升洗涤正庚烷萃取液 ,再将正庚烷萃取液适当浓缩后经过酸化的硅胶固相萃取小柱 ,流出液用N2 吹干后以乙酸乙酯 2 0 0 μL定容 ,对苯并 a]芘进行选择离子监测方式下的气相 质谱法定量测定。方法的分离效果及重现性好 ,可用于复杂体系中痕量组分苯并 a]芘的定量测定。

| Abstract: | A novel method is suggested for the determination of benzoa]pyrene in mainstream smoke. Extraction of Cambridge pads was cleaned up with methanol/n-heptane extraction system and silica solid-phase extraction (SPE). The eluted solution containing benzoa]pyrene was evaporated gently to complete dryness with N2 flow, then reconstituted in 200 microL ethyl acetate for determination with gas chromatography-mass spectrometry selected ion monitoring (SIM). The proposed method had good results and precision for the separation of pyrene in complex matrices. |
