Abstract
A selective and sensitive method to detect polyaromatic hydrocarbons (PAH) using a new solid-matrix room-temperature luminescence technique is presented. The solid-matrix room-temperature fluorescence (SMRTF) and phosphorescence (SMRTP) of PAH can be readily obtained by adsorbing a PAH on Whatman 1PS filter paper. Strong phosphorescence can be detected without adding a heavy atom. Detection limits, ranging from 0.12 to 18 ng, were obtained for several PAH.
