Fluorescence Line-Narrowing Spectrometry of Polycyclic Compounds on Filter Paper Substrates
The fluorescence line-narrowing (FLN) technique was used to characterize polynuclear aromatic compounds adsorbed on a simple and practical substrate consisting of a filter paper material. Narrow-based excitation was used to produce highly resolved fluorescence spectra of benzo[a ]pyrene, chrysene, and pyrene on Whatman 4 paper substrate at 4 K. The detection of these compounds in a complex mixture was illustrated by the analysis of an unfractionated coal liquid sample. © 1986, American Chemical Society. All rights reserved.
