| Abstract: | A new method of derivative constant-energy synchronous fluorescence (CESF) spectroscopy for the simultaneous determination of fluorene, carbazole, benzoa]pyrene and perylene was developed. The comparison and explanation of its performance are presented. The derivative CESF spectra are apparently more structured than the direct CESF. The scanning of derivative CESF is more effective than derivative constant-wavelength synchronous fluorescence spectroscopy. By using this method, real samples (tap water, seawater and airborne particulates) were determined directly and good results were obtained. The recoveries in tap water, seawater and airborne particulates were 90.0%-108.0%, 90.0%-104.0% and 90.0%-102.0% respectively. |
