摘要：

Polycyclic aromatic hydrocarbons (PAHs) widely exist in the atmosphere, soil, and water, and are severely harmful to animals, plants, and humans. Excitation-emission fluorescence matrix coupled with the self-weighted alternating normalized residue fitting algorithm (SWANRF) was proposed to determine the trace concentrations of PAHs phenanthrene, anthracene, and fluoranthene in lake water. Compared with the self-weighted alternating trilinear decomposition method, SWANRF provided more satisfactory concentration prediction results. The average recoveries of phenanthrene, anthracene, and fluoranthene are (99.2±7.2)%, (101.7±7.7)%, and (97.9±5.1)%, respectively. The predicted root mean square error values are 0.240 μg/L for phenanthrene, displacement 0.249 μg/L for anthracene, and 0.247 μg/L for fluoranthene. The experimental results demonstrate that the proposed method is reliable and can achieve simultaneous and rapid determination of trace PAHs in lake water with unknown interference. © 2019, Science Press.
