Direct and selective simultaneous determination of several polycyclic aromatic hydrocarbons by sensitized room temperature phosphorescence in sodium dodecylsulphate micellar solutions was studied. This approach improved, for example, the selectivity factor in determining pyrene in the presence of fluoranthene by a factor of 350, and determined benz[a]anthracene and anthracene in the presence of pyrene...
The sensitized room temperature phosphorescence (SRTP) of pyrene in micellar solutions of sodium dodecylsulfate (SDS) based on triplet-triplet (T-T) energy transfer has been investigated. Triphaflavine as a triplet energy donor, thallium(I) nitrate as a heavy atom, and sodium sulfite as a scavenger of oxygen were used. The effects of triphaflavine, SDS, and thallium nitrate concentrations on pyrene-SRTP...
