Abstract: With the characteristics of high sensitivity, good selectivity and high speed in analysis, fluorescence spectra have been widely used in the identification of oil spill. By combining the synchronous fluorescence spectrometry, derivative spectra and three-dimensional fluorescence spectrometry, this paper analyzes and identifies the spilled oil samples from a harbor. The source of spilled oil is reliably and quickly distinguished, which further illustrates the effectiveness of the fluorescence spectra used in oil spill identification. The study suggests that the synchronous fluorescence spectrometry has poor ability in identifying spilled oil samples with similar origins, while it can preliminarily estimate the similarities. For the three-dimensional fluorescence spectrometry, the generated fluorescence intensities of spilled oil samples are susceptible to a series of factors like weathering. Nevertheless, the overall outline of the map is less affected by interference factors, and the measured results of arenas can accurately reflect the characteristics of the source of spilled oil. As to derivative spectra, the ratio of middle speak can strengthen the spectrum characteristics and enhance the resolving power of the oil spill.
