Abstract In the present paper, a technique of laser-induced fluorescence(LIF)for direct assay of polycyclic aromatic hydrocarbons(PAH) in soil was put forward. The research objective of this article is anthracene. The possibility of using LIF spectra to detect directly anthracene in soil was studied. Anthracene was detected in soil by AvaSpec-3648 Fiber Optic Spectrometer of thermoelectric refrigeration. The authors drew a conclusion that in the range of certain anthracene concentration(0.000 005-0.001 g x g(-1)), the intensity of LIF fluorescence is linear with anthracene concentration in soil, with a regression coefficient of 0. 929. This showed that direct assay of anthracene in soil was feasible by laser-induced fluorescence. The study is important to developing a new analytical technique of quantitative fluorescence detector which can be applied to the analysis of PAH in soil without pretreatment, and is significant to realization of real-time, in-line, in-situ measurement of PAH in soil.
摘要 本文提出了一种利用激光诱导荧光（LIF）直接测定土壤中多环芳烃（PAH）的技术。本文的研究对象是蒽。研究了利用LIF光谱直接检测土壤中蒽的可能性。采用热电制冷的AvaSpec-3648光纤光谱仪对土壤中的蒽进行检测。作者得出结论，在一定蒽浓度范围（0.000 005 - 0.001 g x g(-1)）内，LIF荧光强度与土壤中蒽浓度呈线性关系，回归系数为0.929。这表明利用激光诱导荧光直接测定土壤中的蒽是可行的。该研究对于开发一种无需预处理即可用于土壤中PAH分析的新型定量荧光检测分析技术具有重要意义，对于实现土壤中PAH的实时、在线、原位测量也具有重要意义。
