The possibility of determining pyrene, anthracene, and fluorene in gasoline
by phosphorimetry at room temperature after the micellar extraction with s
odium dodecyl sulfate was examined. It was found that the above polynuclear
aromatic hydrocarbons simultaneously present in gasoline can be selectivel
y determined by room-temperature phosphorimetry using different techniques
for the excitation and population of the triplet states of luminophors (sta
tionary and pulse excitation and triplet energy transfer). The proposed pro
cedure was verified by gas chromatography with a mass-selective detector.
