Enhancement of biodegradability by continuous ozonation in Acid Red-151 solutions and kinetic modeling

The proposed kinetic modeling by Liakou et al. [S. Liakou, S. Pavlou, G. Lyberatos, Ozonation of azo dyes, Water Sci. Technol. 35 (4) (1997) 279-286; S. Liakou, M. Kornaros, G. Lyberatos, Pretreatment of azo dyes using ozone, Water Sci. Technol. 36 (2-3) (1997) 155-163] for another azo dye, namely Orange II, could be satisfactorily applied here, to the continuous ozonation of Acid Red-151, which allowed the prediction of the key variables measured experimentally, regardless of the particular intermediate compounds generated during ozonation.
