Abstract:
General methods for phenol and substitutive phenol in mixing samples could only determine total amount due to the similarity of their UV/vis and fluorescence spectra characteristics.In this paper a highly selective photochemical fluorescence (PCF) method for 2,6-dimethylphenol determination was developed. The method was based on monitoring the photodegradation intermediate of 2,6-dimethylphenol on nanosize meter TiO2 surface. The fluorescence intensity of the intermediate was enhanced in CHCI3 medium and there has a linear relationship between the fluorescence intensity and concentration of 2,6-dimethylphenol. While other phenolic compounds such as phenol,4-methylphenol,o-aminophenol and so on did not interfere.
