Abstract—Electro-Fenton (EF) and Convention Fenton (CF) processes were used to treat the ,wastewater containing nickel, and citric acid as its chelating agent. A stainless steel reactor was used for all the experiments. For the EF experiments, the reactor also served as the cathode while the anode is rod-type titanium metal coated with IrO2/RuO2. The ,nickel, and COD removal were studied. Mere ...
