Abstract:
This paper aims at investigating the stainless steel 304L (SS304L), 316 (SS316) and titanium electrodes used as working electrode carrying out decolorization of Rhodamine B (Rh B) by Electro-Fenton method. In the dual-cell Electro-Fenton system, the decolorization of Rh B was compared by three different cathodes sequentially via the adjusted parameter of operating factors including working potential, initial pH, Fe2+ concentration, supporting electrolyte concentration. The results indicate that the decolorization rate of Rh B was greatest in the case of SS316 and the decolorization approached 64.7% under the suitable condition after 30 min.
