摘要

多环芳烃广泛存在于大气、土壤和水环境中，对动植物和人类有着严重危害。为了快速检测水环境中的痕量多环芳烃（Polycyclic Aromatic Hydrocarbons， PAHs），本文提出利用激发-发射荧光矩阵结合自加权交替归一残差拟合算法（Self-Weighted Alternating Normalized Residual Fitting Algorithm， SWANRF）检测湖水中的菲、蒽和荧蒽。与自加权交替三线性分解方法相比，SWANRF能够给出更满意的浓度预测结果，菲、蒽和荧蒽的平均回收率分别为（99.27.2）%，（101.77.7）%和（97.95.1）%；菲、蒽和荧蒽的预测均方根误差值分别为0.240，0.249和0.247 g/L。实验结果表明，文章提出的方法能够实现未知干扰物共存的湖水中痕量多环芳烃的快速检测，且方法可靠。

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are widely found in the atmosphere

soil and water

which are seriously harmful to animals

plants and humans. In order to rapidly determine the trace PAHs in water environment

the strategy

excitation-emission fluorescence spectroscopy coupled with self-weighted alternating normalized residual fitting algorithm (SWANRF)

was proposed to determine phenanthrene

anthracene and fluoranthene in lake water. Compared with the self-weighted alternating trilinear decomposition method

SWANRF could give more satisfactory concentration prediction results. The average recoveries of phenanthrene

anthracene and fluoranthene were (97.1 6.9)%

(99.1 8.8)% and (96.8 3.8)% respectively. The predicted mean square root error values were 0.250 g L-1 for phenanthrene，0.269 g/L for anthracene and 0.245 g/L for fluoranthene. The experimental results demonstrate that the proposed method can achieve the simultaneous rapid determination of trace polycyclic aromatic hydrocarbons in lake water with unknown interference

and the method is reliable.
