摘要：

Room-temperature phosphorescence (RTP) characteristics of 27 banned drugs in sport on Whatman No. 1 filter paper were studied. Several heavy-atom perturbers, including I-, Tl+ and Pb2+, and the effect of pH were investigated. Optimum experimental conditions for every case were evaluated. The phase plane method was applied to the determination of phosphorescence lifetimes on a filter-paper substrate. Compared with RTP, laser-induced phosphorescence spectrometry provides lower limits of detection.
