Oxone® induced textile dyes degradation using cobalt-doped alumina catalyst

Cobalt-doped alumina catalyst calcined at 500 ?C (CoA-500) was investigated in the degradation of anionic textile dye Orange G in the presence of Oxone?. Different reaction parameters were altered in order to study their influence on Orange G degradation. The increase of the Oxone? dosage, mass of the catalyst and temperature was beneficial for the dye degradation rate. The best catalytic performance was obtained in the range of the initial solution pH = 6-8. Simultaneous degradation of both Orange G and cationic textile dye Basic blue 41, was also tested. The degradation of the Basic blue 41 did not occur while Orange G was present in the system. CoA-500 was found to be efficient catalyst in the Oxone? induced catalytic degradation of textile dyes.
