Fund Project:

A derivative constant-energy synchronous fluorescence spectroscopy for rapid and simultaneous analysis of four polynuclear aromatic hydrocarbons(PAHs):2,3-benzofluorene, benzo[α]pyrene, 3,4,8,9-dibenzopyrene and 2,3-benzoanthracene has been developed. Only a single scan is needed for the simultaneous identification and quantitative determination of above-mentioned PAHs. The detection limit for 2,3-benzofluorene, benzo[α]pyrene, 3,4,8,9-dibenzopyrene and 2,3-benzoanthracene is 0.22×10^-9, 0.52×10^-9, 0.46×10^-9 and 0.24×10^-9 g/mL, respectively. By using this method, the four PAHs in real samples were determined directly and with good results. The recovery of PAHs in tap water, seawater and airborne particulates was 87%~99.5%, 88%~101% and 84%~105% respectively.
