Abstract

This paper reports a method for the spectrofluorimetric identification of fourteen polycyclic aromatic hydrocarbons (PAHs) at the nanogram per mililitre level in pure samples. The total fluorescence spectrum is scanned asynchronously to record the fluorescence intensity at 15 preset excitation-emission wavelength pairs. By calculating a match index between the unknown sample and a library of standard samples, the fourteen PAHs can be correctly identified. The match index obtained was always greater than 0.95.
