The present article describes the simultaneous phosphorimetric determination of pyrene and benzo[a]pyrene, two highly toxic polycyclic aromatic hydrocarbons, through excitation–emission phosphorescence matrices (EEPMs) and second-order calibration. The developed approach enabled us to determine both compounds at μgL −1 concentration levels without the necessity of applying separation steps,...
The influence of different factors on the room-temperature phosphorescence (RTP) emission from the inclusion complex between α-cyclodextrin (α-CD) and 6-bromo-2-naphthol (BN) was analyzed. Although RTP signals are detected even in aerated solutions, an efficient enhancement of the phosphorescence emission (about 13 times) is obtained when the solutions of the complex are deaerated with nitrogen bubbling,...
