Benzo[k]fluoranthene (BkF) and perylene (Per) are among the sixteen priority pollutants of polycyclic aromatic hydrocarbons recommended by The United States Environment Protection Agency (EPA). In this paper, we report a simple and rapid method for quantitative analysis of BkF and Per using the three-dimensional excitation-emission matrix (EEM) fluorescence coupled with parallel factor analysis (PARAFAC). Before analyzing of two mixtures quantitatively, we study the fluorescence characterization of pure BkF and Per first. The maximal peak values are at 306 nm of the excitation wavelength and 406 nm of the emission wavelength for BkF, and 252 and 438nm for Per, the linear ranges of BkF and Per are 0.8~16~ L-1 and 0.6~20~ L-1 respectively. Finally the average recoveries are obtained using PARAFAC algorithm, which can reach 101.1% and 99.5% for BkF and Per respectively. In order to evaluate the accuracy of the PARAFAC algorithm, selectivity (SEL) and sensitivity (SEN) have also been presented. Results show that a good performance has been achieved using excitation-emission fluorescence coupled with PARAFAC algorithm.
