The rate of catalytic degradation of Orange II, in aqueous solution, in the presence of Mn(II) salts and peracetic acid increased with concentrations of catalyst and peracid, decreased with increasing carbonate buffer concentration, and approached a maximum at pH 9.4. Experiments with different in situ formed intermediates showed the essential role of a small amount of HP (present in commercial peracetic acid) for efficient catalytic decomposition of the dye. HP was shown to play a crucial role as a reducing agent in the catalytic cycle (Scheme 25). ... 

A study of the degradation of two azo disperse dyes. Disperse Orange 5 [6232-56-0] (1) Cl 11100) and Disperse Red 5 [3769-57-1] Cl 11215) showed reduction of the azo linkage into aromatic amines and further dealkylation to -phenylene-diamine [106-50-3] (2) (255).
