Electro-combustion of Pyridazine using a Boron-Doped Diamond Anode

Disposal of industrial wastewater containing pyridazine compound by electrochemical methods has been studied in this paper. It was found that only a small fraction of the organics was oxidised by direct electrolyses, while complete mineralisation of the organics was obtained with the indirect process, electrogenerating hypochlorite from chloride oxidation. The effects of operating factors, such as concentration of pyridazine, current density and chloride concentration, were also investigated. The experimental data suggested that the Boron-Doped Diamond Anode (BDD) had the highest electrocatalytic activity and increasing the chloride concentration in the electrolyte resulted in an increasing of COD and electro- oxidation removal.
