The electrochemical degradation of synthetic dye wastewater containing Acid Orange II was performed in a continuous reactor using Ti/IrO₂-Pt as anode. The effects of electrolyte, current density, initial concentration, electrodes distance and circulation flowrate on the degradation efficiency of Acid Orange II were studied. The changes of the UV-Vis absorption spectra during electrolysis were monitored and used to investigate the capacity of Ti/IrO₂-Pt anode. The experimental results showed that, the presence of chloride in the dye wastewater could promote the degradation efficiency significantly, and increasing the dosage of NaCl and current density were helpful for removal of Acid Orange II rapidly. With the increasing of initial concentration, the required time for complete removal of Acid Orange II was extend. The degradation was less efficient with too high circulation flowrate and too far electrodes distance. With the current density of 10 mA/cm², NaCl dosage of 0.005 M, electrodes distance of 10 mm and circulation flowrate of 300 mL/min, the Acid Orange II of 50 mg/L was degraded completely within 30 min. During electrolysis, the Ti/IrO₂-Pt anode could mineralize the Acid Orange II unselectively. The results of this study could provide the basic information for the application of dye wastewater degradation with Ti/IrO₂-Pt anode.
