The polycyclic aromatic hydrocarbons (PAHs) fluorene, acenaphthene and phenanthrene have been determined in water at trace levels by solid-phase variable-angle synchronous scanning spectrofluorimetry. These PAHs were previously fixed on Sephadex G-15 gel, and then packed in a quartz cell with a 1-mm pathlength. The fluorescence of the PAHs-gel system was measured directly using a solid-surface attachment...
The inclusional complexation between γ-cyclodextrin and acenaphthene in aqueous solution was investigated by spectroscopic techniques. A 1:1 complex was detected and its formation constant was determined. After adding bromoalcohols such as 2,3-dibromopropane-1-ol or 2-bromoethanol both a decrease of the fluorescence and an enhancement of the room-temperature phosphorescence (RTP) of acenaphthene were...
