摘    要:多环芳烃作为普遍关注的优先监测污染物,在水环境中其含量很低,易受共存物腐殖酸的干扰.由于多环芳烃与腐殖酸的光谱重叠严重,很难用常规方法快速的定量检测.菲(PHE)作为多环芳烃中的模式化合物,对菲和腐殖酸(HA)的荧光光谱特性进行了研究,分析了腐殖酸共存下对菲定量检测的影响.采用平行因子算法分析混合液的三维荧光光谱,在激发波长为240~360 nm(5 nm为间隔)、发射波长为260~575 nm(5 nm为间隔)下对该体系进行了分辨研究,并对菲和腐殖酸进行荧光光谱测量.实验结果表明,此方法可用于有干扰共存下多环芳烃化合物的直接快速定量检测.

关 键 词:三维荧光光潜  荧光光谱重叠  PARAFAC算法    腐殖酸

Abstract:Polycyclic aromatic hydrocarbons as a universal concern in the monitoring of priority pollutants have low content in the water environment and are interfered with the coexistence of humic acid. The spectra of humic acid and polycyclic aromatic hydrocarbons overlap seriously,so it was difficult to use the conventional methods for rapid quantitative detection. As a model compound of polycyclic aromatic hydrocarbons,Phenanthrene (PHE) was chosen in the experiment. The fluorescence spectra of PHE and humic acid...
Keywords:Three-dimensional fluorescence spectra  Overlapping of fluorescence spectra  PARAFAC  Phenanthrene  Humic acid
