| Abstract: | The fluorescence spectra of 3-bromine-N-ethyl-phenothiazine with various acid degrees and different polarity surfactants in aqueous solutions were studied in detail. The reasons why fluorescence spectra of Br-Pwere very sensitive to environmental polar and acid changes were discussed based on Lewis acid-base theory. Meanwhile the spectrum of Br-P under ultraviolet ray illumination showed that Br-P had kinetic fluorescence. The method is not only simple but also sensitive with low limit of detection. The calibration curves were linear between 1 x 10(-7) and 1 x 10(-4) mol/L, with a regression coefficient of 0.9995 and RSD<2.8%. |
