A novel method for the determination of trace naphthols was proposed based on naphthols, potassium bromate and pyronine Y in dilute sulfuric acid medium can react to form ion-association complexes, which not only resulted in the changes of the three-dimension fluorescence spectra, absorption spectra and the quenching of fluorescence, but also resulted in the great enhancement of resonance light scattering (RLS). The characteristics of RLS spectra, the effective factors and optimum conditions of reaction were studied. It was found that the enhanced intensity of RLS at 396 nm was proportional to the concentration of 1-naphthol and 2-naphthol in the range of 41.4 approximately 3024 ng mL(-1) and 38.3 approximately 3068 ng mL(-1), respectively. The urine samples analysis of the relative standard deviation was 3.1-7.1% and the average recovery was 96.0% (n=6). The present method had been applied to the determination of trace naphthols in human urine, the obtained results were in good agreement with those obtained by the HPLC method; moreover, we had carried on an initial study of the reaction mechanism in terms of spectral characteristics.
