説明
It has been reported that the fluorescence intensity of carbazole can be selectively measured by the additions of sodium methoxide, potassium iodide, and methanol to dimethyl sulfoxide solution of the sample. The fluorescence intensities of interfering polynuclear aromatic compounds decreased because the intensities of the interfering substances are quenched by the potassium iodide and the fluorescence maximum of carbazole is shifted to longer wavelength by the ionization with sodium methoxide. In the present investigation, the applicability of this method to the determination of benzocarbazoles was studied. The results indicated that the fluorescence intensity of 5H-benzo[b]carbazole was stable and measured without interferences of 11H-benzo[a]carbazole and 7H-benzo-[c]carbazole. 5H-Benzo[b]carbazole could be determined by measuring the fluorescence intensity at 533nm with excitation at 470nm. This method could be applied for the determination of 5H-benzo-[b]carbazole in commercial carbazole. The limit of the determination was 0.01%.
