An electro-Fenton system using magnetite coated metallic foams as cathode for dye degradation

An electro-Fenton system using magnetite coated metallic foams as cathode for dye degradation
An electro-Fenton system with a magnetite washcoated metal foam as cathode and graphite as anode was successfully applied for the discoloration of methylene blue in aqueous. The effect of pH, applied voltage, supporting electrolyte, electrode inner space, and catalyst dosages were investigated and optimized. Using this cathode, methylene blue was removed with >99.8% removal rate at 10ppm after 60min and with >95.2% at 50ppm after 120min of reaction. Furthermore, those cathodes could be reused at least three times without performance degradation. Due to high degradation capability, simple recovery and high reusability, magnetite washcoated metal foams could be an effective cathode for electro-Fenton systems for removing dyes in wastewater.
