应用荧光法分析汽油燃烧残留物

An Analysis of Gasoline Combustion Residues by the Use of Fluorescence Spectra

通过应用三维荧光光谱法,对比分析了汽油、煤油、柴油及其燃烧残留物的三维荧光特征参数,主要分析了荧光峰位置、半峰宽、荧光发光区域分布、次峰与主峰的荧光强度比等,验证了荧光光谱法在鉴别火场汽油助燃剂燃烧残留物中的可行性,为火灾原因调查提供更多依据。

In this paper,three- dimensional fluorescence spectroscopy is used to identify gasoline,kerosene,diesel and their combustion residues by analyzing the parameters of locations of peaks,half- band widths of peaks,the intensity ratios of peaks and light- emitting region in the three- dimensional fluorescence spectra. Thus,the analysis verifies the feasibility of the fluorescence spectroscopy in identifying the combustion residues of gasoline in fire in order to offer more information to the fire investigation.
