Abstract

Abstract: Electrolysis-generated water treatment FeO^2-₄ was prepared in a diaphram cell with double cathodic chamber and porous cylindrical cast iron anode.The experiment result showed that current efficiency and FeO^2-₄ concentration were higher by using double cylinder cast iron anode.Optimum result was obtained at J=30 mA•cm^-2,30℃,14 mol•L^-1 NaOH.70 mmol•L^-1 FeO^2-₄ 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.
