Electrochemical Degradation of Acid Blue 41 on Ti/Sb-SnO₂ Anodes

Abstract:

The electrochemical degradation of the wastewater of acid blue 41 was studied with Ti/Sb-SnO₂ as an anode in which the Sb-SnO₂ coating was prepared with a polymeric precursor method. The conversion of acid blue 41 was carried out under galvanostatic control. The effects of current density, initial concentration of acid blue 41 and the concentration of supporting electrolyte on color removal, COD removal and instantaneous current efficiency (ICE) were investigated. The experimental results show that the color removal and COD removal enhance with increasing current density, but ICE decreases. Acid blue 41 can firstly be oxidized by the destroying the conjugated chromophore group and it is difficult that the intermediates produced during the degradation process of cid blue 41 is further degraded.
