ASE萃取—HPLC法测定烟气中多环芳烃

通过试验建立了加速溶剂萃取—高效液相色谱法测定烟气中15种多环芳烃的方法,优化了实验条件。方法线性关系良好,15种多环芳烃的检出限在0.003~0.1 ng/m3之间,空白加标实验的相对标准偏差RSD在2.7%~8.9%之间,基质加标回收率在62.5%~107.5%之间。实际样品的测定结果表明,该方法分离效果好,能够满足烟气中多环芳烃分析的要求。

Determination of PAHs in Flue Gas with ASE Extraction and HPLC

The accelerated solvent extraction—high performance liquid chromatography method is established for determination of 15 polycyclic aromatic hydrocarbons in flue ways to optimize the test conditions.Linear relationship is good,the detection limit of 15 kinds of polycyclic aromatic hydrocarbons is between 0.003～0.1 ng/m3,blank spike test the relative standard deviation between 2.7%～8.9%,and the matrix recoveries is 62.5%～107.5%.The sample analysis results show that the separation effect,able to meet the requirements of the analysis of polycyclic aromatic hydrocarbons in the flue gas.
