同步荧光光谱分析法在海面溢油鉴别中的应用研究

摘要

为了实现海面溢油快速筛选和鉴别,文章提出了应用同步荧光光谱技术结合系统聚类分析方法鉴别海面溢油的方法,并应用于不同原油样品及风化油样的分析.结果表明,选择波长差为25 nm,采用300～500nm范围内数据进行聚类分析,可以将原油样品和风化样品完全区分开,不同海区、不同采集时间的原油样品可大致分开.作为溢油鉴别的一种辅助方法,同步荧光光谱分析法能够对可疑油源及溢油样品实现初步筛选.%In order to screen and identify the source of spilled oils at sea, synchronous fluorescence scans combined with clustering analysis are proposed and applied to different crude oil and weathering crude oil. SFS data of △l=25 nm were recorded and dealt with clustering analysis. The cluster results of SFS data in the range of 300 ～ 500 nm show that the crude oil and the weathering oil could separate completely. And the crude oils from different sea areas, also collected at different time, clustered into different groups, respectively. The results indicate that this method could preliminarily selected, and maybe serves as an assistant method in oil spill identification.
