Electrolysis-generated water treatment FeO2-4 was prepared in a diaphram cell with double cathodic chamber and porous cylindrical cast iron anode.The experiment result showed that current efficiency and FeO2-4 concentration were higher by using double cylinder cast iron anode.Optimum result was obtained at J=30 mA8226;cm-2
30℃
14 mol8226;L-1 NaOH.70 mmol8226;L-1 FeO2-4 was produced and current efficiency was 36.8% for 5.5 h electrolysis. The result of ferrate oxidative degradation of benzidine wastewater showed removal rate of CODCr about 85% and the final products were small molecule inorganic compounds.
