Spectral-kinetic relationships for the room-temperature phosphorescence ofpolycyclic aromatic hydrocarbons in micellar solutions

Lifetimes of tripler sates of molecules of different polycyclic aromatic hy drocarbons are measured in the system 0.1 M sodium dodecyl sulfate-0.025 M thallium nitrate-0.01 M sodium sulfite are measured, and the dependences of these quantities on the spectral luminescence characteristics are determin ed. Based on the obtained results, the application range of room-temperatur e phosphorimetry with time and spectral selection for the determination of individual polycyclic aromatic hydrocarbons in mixtures is determined.
