Abstract :

In this study, the degradation of 4-nitrophenol in aqueous environments was studied by Electro Fenton and Electro Persulphate in electrochemical batch reactor equipped with four iron electrodes and a direct power source. The results showed that the removal of 4-nitrophenole in Electro-Persulphate and electro Fentone were 99.2% and 94% at optimum operation condition including operational pH at 3, the initial concentration of 4-nitrophenol at 100 mg / l, hydrogen peroxide and persulphate at 0.5 mM, with the density of 0.1 A/dm2  and 60 min of reaction. The research results showed that the processes of electro-persulfate and electro-fenton had the same elimination efficiency in acidic media for 4-nitrophenol removal and, in general the combination of electrochemical with persulfate and hydrogen peroxide for electrical production of iron and activation of persulfate and hydrogen peroxide had more ability compared to separate use. The  removal percent of COD in real wastewater samples with the initial COD of 5000 mg/l were 82 and 86% in ElectroFenton and Electro-persulfate processes, respectively.
