Time selection in the room temperature phosphorescence method for the analysis of mixtures of polycyclic aromatic compounds in micellar solutions

It is proposed to use the time selection principle in the laser-induced roo m temperature phosphorescence method. Optimal conditions are determined for the detection of room temperature phosphorescence of different polycyclic aromatic hydrocarbons in micellar systems. It is demonstrated that the spec ific features of room temperature phosphorescence in micellar solutions are long lifetimes of excited triplet states and the absence of interaction be tween individual compounds in mixtures. These features made it possible to use this method for the simultaneous determination of some polycyclic aroma tic hydrocarbons in mixtures.
