oxidative Degradation - Opis:
- The oxidative decomposition reactions of fuchsine dye on the surface of nano-catalyst Cu0.5Pb0.5ZrO3 were studied carefully in an aqueous solution in the presence of H2O2 under condition of pseudo-first order reaction. The catalyst was prepared by solid state route using pure nominal composition of metal oxides. The structural and micro-structural properties of the catalyst were characterized well by XRD, SEM and AFM respectively. Many of the kinetic parameters were investigated in this article, results obtained indicated that, the rate of oxidative degradation of acid fuchsine dye was found to be pH-dependent. The mechanism was proposed and the activation parameters were calculated.
