Abstract
The applicability of nonprotected room-temperature phosphorescence (NP-RTP) in real samples is demonstrated in this work. In this methodology only two reagents, potassium iodide and sodium sulfite, were used to obtain the phosphorescent signals. Synchronous phosphorimetry was used to enhance sensitivity. Analyses of dibenzofuran, acenaphthene, and fluorene were carried out in a sample of impure fluorene.
