A method for the simultaneous determination of polycyclic aromatic hydrocarbons (PAHs) was developed by means of fluorometric analysis combined with partial least squares regression (PLS) analysis. Fluorescence spectra (Ex=305nm, Em=330-520nm) of twenty one synthetic solutions, which contain five sorts of PAH (10-2-10-1 μ g cm-3) in n-hexane, were converted into ASCII data set. These were imported into a microcomputer and modified to make a regression model by employing PLS software. Newly prepared mixtures of all five PAHs (Benzo [a] pyrene, Perylene, Fluoranthene, Pyrene and Chrysene) were analyzed simultaneously using this model. The results predicted were in good agreement with the real data.
