| Abstract: | The possibility of determining pyrene, anthracene, and fluorene in gasoline by phosphorimetry at room temperature after the
micellar extraction with sodium dodecyl sulfate was examined. It was found that the above polynuclear aromatic hydrocarbons
simultaneously present in gasoline can be selectively determined by room-temperature phosphorimetry using different techniques
for the excitation and population of the triplet states of luminophore (stationary and pulse excitation and triplet energy
transfer). The proposed procedure was verified by gas chromatography with a mass-selective detector. |
