Using an anodic Fenton process for degradation of nitrobenzene in waste water

The paper deals with the degradation of nitrobenzen e (NB) by advanced catalytic oxidation based on an anodic Fenton’s reagent. . Th e degradation or the conversion of nitrobenzene in to CO 2, H2O and other minerals was performed by electrochemical method in the electrolysis system with direct curre nt, with the iron anode section volume of 53ml, with potential 2.5 V, consisting of EDTA (1mM), O 2 (10mg/l), Na 2SO 4 (0.1M), the graphite cathode section volume of 53m l consisting electrolyte of Na 2SO 4 (0.1M). Concentrations of NB during electrochemical degradation were monitored using high-performance liquid chromatography, (HPLC, Aligent USA). The electrochemical degradation of NB can be explai ned by the free radical OH • generated during electrolysis using direct current with iron anode in presence of EDTA, oxygen in weak acid pH ‐ solution.
