Catalytic oxidative degradation of a textile dye Orange G was investigated in the reaction
system where oxidant Oxone® was used as a source of SO4˙ˉ anion radicals. Cobalt-doped
alumina was tested as a heterogenous catalysts for Oxone® activation. The catalyst was
synthetized and calcined at 500 °C. The influence of different reaction parameters was
followed: the Oxone® dosage, Orange G concentration and initial pH of the reaction solution.
The Oxone® dosage was varied from 10 mg to 80 mg. Small differences in degradation
efficiency were observed but mass of 40 mg of Oxone® was found to be optimal in the first
hour of the reaction. The effect of the Orange G concentration was investigated in the range
from 20 mg dm-3 to 50mg dm-3. For the concentration of 20 mg dm-3 the reaction was much
faster than for other investigated concentrations. The effect of the pH was tested in the range
from 2 to 9. The optimal pH range was found to be between 6 and 9, but reaction was feasible
a...lso for lower pH. It can be concluded that investigated catalyst is applicable with high
efficiency in the wide range of Oxone® dosages, dye concentrations and initial pH values.
