Abstract: Derivative variable-angle synchronous fluorescence spectroscopy is developed to improve the selectivity of fluorescence measurement.The second derivative variable-angle synchronous scanning permits the rapid simultaneous determination of 1-naphthol and 2-naphthol in a mixture from a single spectrum based on a single scan, whereas twice scanning procedure should be required using second derivative constant-wavelength synchronous fluorescence spectroscopy and the quantitative analysis of 1-naphthol in a mixture could not be performed with direct variable-angle synchronous fluorescence spectroscopy.6.7-2000 ng/mL 1-naphthol and 3.6-500 ng/mL 2-naphthol can be quantified with relative standard deviations of l.3%-2.6%.
