土壤有机质与多环芳烃混合物荧光光谱的辨析

Discrimination of Fluorescence Spectra of the Mixture of Soil Organic Matter and Polycyclic Aromatic Hydrocarbons(PAHs)

土壤有机质的荧光干扰一直是土壤中PAHs精准检测的瓶颈。文章基于三维荧光光谱技术结合平行因子算法对土壤有机质与PAHs混合物进行辨析。实验结果表明,该方法可有效完成土壤有机质与PAHs混合物的分解与判定,为研究PAHs精准定量分析提供依据。

Fluorescence interference of soil organic matter has been the bottleneck of accurate detection of polycyclic aromatic hydrocarbons（PAHs） in soil. Based on three-dimensional（3 D） fluorescence spectroscopy and parallel factor algorithm, the mixture of soil organic matter and PAHs was identified. The experimental results show that this method can effectively decompose and judge the mixture of soil organic matter and PAHs, and provide a basis for the accurate quantitative analysis of PAHs.
