| 摘 要： | 通过传统单波长激发/发射荧光光谱法与恒能量同步荧光光谱法进行对比,对大气颗粒物中多环芳烃(PAHs)进行了定性定量分析,采用恒能量同步荧光光谱法在不同能量差下建立了15种典型PAHs成分的恒能量同步荧光法的标准谱库.在各PAHs在最佳能量差下进行定量分析,结果表明,除苊荧光信号响应较差外,其余PAHs的LOD和LOQ分别为0.0580～3.18、0.232～12.7 ng·mL~(-1).15种PAHs的空白和一定浓度下的加标回收率范围在82.8%～120.0%,相对标准偏差范围在0.51%～5.87%之间,以恒能量同步荧光光谱进行了兰州地区大气颗粒物中15种PAHs分布特征分析.

| Abstract: | In this paper, traditional single-wavelength excitation/emission fluorescence spectroscopy was compared with constant-energy synchronous fluorescence spectrometry to qualitatively and quantitatively analyze PAHs in atmospheric particles. Constant-energy synchronous fluorescence spectrometry was used to establish 15 PAHs under different energy differences. Standard spectral database of 15 PAHs for constant energy synchrotron fluorescence was developed. Quantitative analysis was performed at the optimal energy difference for each PAHs with LOD and LOQ of 0.0580 ~3.18 and 0.232~12.7 ng·mL-1, respectively. The recoveries of the 15 PAHs in the blank and at certain concentrations ranged from 82.8% to 120.0%, and the relative standard deviations ranged from 0.51% to 5.87%. The actual samples were analyzed at monitoring sites of Lanzhou, China. |
