| 摘 要： | 多环芳烃(简称PAHs)具有高荧光量子产率,利用三维荧光光谱研究了PAHs中菲的荧光光谱特性.菲具有两个荧光峰.通过对菲的三维荧光光谱的分析,选择在激发波长255 nm、发射波长370 nm对菲进行定量分析.菲溶液在5.0～250.0 ng·mL-1的范围内工作曲线呈线性关系,检出限为3.88 ng·mL-1,相对标准偏差为4.23%(n=5),实验还尝试了对自来水样品的测定,测试效果良好,回收率为90.0%～105.4%.该研究为快速检测水源水中痕量PAHs提供了方法基础. |

| Abstract: | According to the high fluorescence quantum yields of polycyclic aromatic hydrocarbons(PAHs),the fluorescence spectra of phenanthrene were investigated by three dimensional fluorescence excitation-emission matrix(3DEEM).The results show that the three-dimensional fluorescence spectra of phenanthrene in aqueous solution mainly have two fluorescence peaks.On the basis of three-dimensional fluorescence spectrometry analysis of phenanthrene,the excitation wavelength of 255 nm and emission wavelength of 273 nm we... |
