Study of electrocatalytic degradation of acid orange 7 on boron-doped diamond electrode

In the present work, the degradation of acid orange 7 was studied by the electrocatalytic anodic oxidation through the use of boron-doped diamond (BDD) electrode. A factorial design analysis was adopted to evaluate the effects of operating parameters on the treatment performance. Five operating parameters including treatment time, flow rate, applied current, initial concetration and electrolyte concentration were chosen as test factors. Of the five test factors involved, treatment time, applied current and initial concentration had considerable contributions on the treatment performance. Additionally, the remaining two factors possessed less influences on the treatment efficiecy. The result obtaied, suggested that the factorial design analysis was of great use to the parameter optimization of BDD electrocatalytic treatment.
