Towards understanding of heterogeneous Fenton reaction using carbon-Fe catalysts coupled to in-situ HO electro-generation as clean technology for wastewater treatment.

Iron-supported catalyst on granular activated carbon was prepared for its use in heterogeneous Fenton reaction coupled to an in situ HO electro-generation. For this process, an electrolysis cell was employed, using carbon felt as cathode and graphite as anode. A solution of HO (electrogenerated at a rate of 30 mg L h) was obtained using a current intensity of 12 mA.
