Abstract
Cobalt-doped alumina catalyst calcined at 500 ºC (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.
