..cap alpha..-cyclodextrin-induced solid-surface room-temperature luminescence (CISS-RTL) was used to characterize synthetic mixtures of polynuclear aromatic hydrocarbons (PAH) adsorbed on ..cap alpha..-cyclodextrin-sodium chloride mixtures. With CISS-RTL, qualitative analysis of binary mixtures of benzo(a)pyrene and benzo(e)pyrene was easily accomplished even at nanogram levels. In addition, a technique was also developed that was used in characterizing a nine-component PAH mixture. This method employs extraction, selective excitation, and detection by CISS-RTL and solution fluorescence spectroscopy. Nine PAH of various sizes ranging from a two-ring compound (naphthalene) to a ten-ring compound (decacyclene) were selected as model compounds, and several synthetic mixtures containing different amounts of the nine PAH were prepared and were analyzed by this approach. The results showed that between seven to nine PAH were identified in the mixtures at nanogram levels.
