Electrochemical oxidation experiments for acid red B wastewater using Ti/RuO2-IrO2 plate as anode and anthraquinone-modified graphite felt as cathode, were studied respectively. The effects of current, electrolyte concentration, electrolytic time, spacing of plate and the initial pH value on the electrochemical degradation of acid red B were investigated. The results showed that when the concentration of acid red B was 200 mg/L, electric current was 3 A, electrolyte concentration was 0.02mol/L, electrolytic time was 30 min, spacing of plate was 1 cm, and initial pH value was 5.0, the acid red B removals and current efficiency could reach 91.66% and 12.71% respectively. The electrochemical degradation process of acid red B was approximately complied with the first-order kinetics equation ln (c0 / ct) = 0.069 9 t - 0.036 1.
