    Determination Method for Polycyclic Aromatic Hydrocarbons in Ambient PM2.5

      摘要
    • 摘要:
      目的 建立一种便捷、高效的方法来检测大气细颗粒物（PM2.5）中的16种多环芳烃（PAHs）。
      方法 乙腈—超声水浴萃取样品中的PAHs，经过ENV固相萃取柱净化，多环芳烃专用色谱柱分离，再用液相色谱—荧光—紫外检测器串联进行检测。
      结果 16种PAHs在线性范围内有良好的线性关系，相关系数均≥0.999 9，检出限范围为（0.04~0.26）ng/m3，平均回收率为85%~114.1%，相对标准偏差均小于8.0%。
      结论 本方法提取过程简单、灵敏度高、精密度高，适用于PM2.5中PAHs的污染分析。

       

      Abstract:
      Objective To establish a convenient and efficient method to detect 16 polycyclic aromatic hydrocarbons (PAHs) in PM2.5.
      Methods PAHs were extracted from samples via acetonitrile-ultrasonic water bath, purified by ENV solid-phase extraction column, separated by polycyclic aromatic hydrocarbon special chromatographic column, and then detected by liquid chromatography-fluorescence ultraviolet detector in combination.
      Results Sixteen kinds of PAHs had a good linear relationship within their respective linear range, and the correlation coefficients were all higher than 0.999 9. The range of limit of detection is (0.04~0.26) ng/m3, the average recovery rate is 85%~114.1%, and the relative standard deviations are all less than 8.0%.
      Conclusions This method has simple extraction process, high sensitivity, and high precision, and is suitable for the pollution analysis of PAHs in PM2.5.
