摘要：

For in situ and on-line detection of polynuclear aromatic hydrocarbons (PAHs) in water, a fibre-optic sensor system with a fibre length of 50 m is presented. Laser-induced, time-resolved fluorescence spectroscopy allows detection limits in the ng l-1 range. Analytical figures of merit are given for thirteen environmentally relevant PAHs in water. First results for a binary mixture of fluoranthene and pyrene are presented. A deconvolution algorithm is described that simplifies the analysis of time-resolved emission spectra of single- and multi-component PAH mixtures.
