- Abstract
- The contribution of two- to seven-ring polycyclic aromatic
hydrocarbons (PAH) and of larger aromatic structures
contained in complex PAH-laden mixtures collected in
flames was evaluated by fluorescence spectroscopy. A
composition procedure of the fluorescence spectra of
individual PAHs, analyzed by gas chromatography/mass
spectrometry (GC/MS) was applied for the evaluation of
their contribution to the fluorescence spectra of PAHladen
mixtures. In this way, it was possible to put in
evidence the contribution to the total fluorescence spectrum
of high molecular weight aromatic species present
in the PAH-laden mixtures and not detectable by GC/MS.
Qualitative and quantitative interpretation of synchronous
and conventional fluorescence spectra of PAH-laden
mixtures formed in combustion processes was proposed.
The composition procedure was showed to be reliable in
the UV-visible region for samples dissolved in cyclohexane
solutions, but failed in the UV region when the solvent
contained heavy atoms, as in the case of dichloromethane.
However, the heavy-atom solvent effect was not sufficient
to explain the depression of the UV fluorescence signal.
Energy transfer interaction between fluorene and other
fluorescing PAHs was suggested to be also responsible
for this effect on the basis of fluorescence studies performed
on single PAHs and their mixtures in cyclohexane,
methanol, and dichloromethane. (literal)
