Abstract

The catalytic performances of LaBO₃ (B: Fe,
Co, Mn, Ni) perovskite catalysts in Fenton-like oxidation of the textile dye,
Reactive Black 5 were compared, and, the optimum reaction conditions were
investigated in the presence of the most efficient catalyst. Reactive Black 5
was selected as the model dye due to its complex chemical structure, high water
solubility and common usage in the textile industry. The performances of the
catalysts in Reactive Black 5 degradation and decolorization were compared by
testing different catalyst loadings. According to the catalyst screening
experiments, LaFeO₃ showed the highest catalytic performance whereas
LaCoO₃, LaMnO₃, and, LaNiO₃ were not effective
in the degradation and decolorization of Reactive Black 5. A parametric study
was carried out in the presence of LaFeO₃ catalyst in order to
determine the most suitable reaction conditions. In the parametric study, the
effect of catalyst loading, pH and the initial H₂O₂
concentration were investigated. The initial dye concentration and the reaction
temperature were kept constant at 100 ppm and 50℃, respectively. The most suitable reaction conditions
were determined as 0.1 g/L of catalyst loading, 3 and 1 mM of H₂O₂,
and, 96.9% degradation, and complete decolorization were achieved under these
conditions.
