doi:10.7517/j.issn.1674-0475.2004.05.383

Abstract

Abstract: The photocatalytic reaction of reactive brilliant red X-3B aqueous solution was studied.During the photocatalytic processes,ultraviolet-visible spectrophotometer,high performance liquid chromatograph and mass spectrograph were applied to investigate the composite changes of reactive brilliant red X-3B aqueous solution,and the COD values of reactive brilliant red X-3B aqueous solution were measured by dichromate titration method,the adsorptive species on the surface of catalysts were tested by Fourier transform infrared spectrometer.The results indicated that,the photocatalytic decoloration and degradatin processes were taken place simultaneously under our experimental conditions.Some species which difficult to mineralize were produced in the solution after decoloration process,so that,the mineralization process was difficult to proceed.

Key words: photocatalysis, reactive brilliant red X-3B, decoloration, mineralization
