Study on the Treatment of High Concentration Dye Wastewater on Modified Active Carbon Cloth Electrode

Abstract:

In this study, for the ﬁrst time nanostructured TiO2 and Fe2O3 was loaded on active carbon cloth (ACC) as electrodes to be used in an electrochemical oxidation system. This novel TiO2-ACC and Fe2O3 / TiO2-ACC composite electrodes(or modified electrodes) were characterized by scanning electronmicroscopy (SEM)and cyclic voltammetry(CV).During the degradation of dye wastewater, electrochemical oxidation system with TiO2-ACC and Fe2O3 / TiO2-ACC electrodes showed much higher activity than with ACC electrodes. The system with Fe2O3 / TiO2-ACC electrodes acquired the best COD removal: the COD of wastewater decreased from 33000 mg/L to 8700mg/L. The removal rate of COD reached 74%, which was 19% higher than ACC system.
