   Abstract:
   This study investigated a simple technique based on sensitized luminescence for detecting trace amounts of polynuclear aromatic (PNA) compounds. Anthracene was used as the sensitizer designed to absorb excitation energy and funnel it to the guest analyte compounds spotted on anthracenetreated filter paper. The data indicate that anthracene can improve the fluorescence signal of various PNA compounds such as perylene and benzo[a]pyrene by 2 orders of magnitude. For other compounds such as fluoranthene, no fluorescence sensitization by anthracene was observed. The usefulness of the sensitized fluorescence detected by a fiber-optics luminoscope device for screening complex samples is illustrated in analyses of a coal liquid and an air particular sample extract. © 1986, American Chemical Society.
