The electrochemical mineralization of organic pollutants is a new technology for treatment of dilute wastewater (COD < 5 g L -1 ). In this method, use of the electrical energy can produce complete oxidation of pollutants on high oxidation power anodes. An ideal anode for this type of treatment is a boron-doped diamond electrode (BDD) characterized by a high reactivity towards oxidation of organics. In the present work kinetic aspects of organic mineralization is discussed. The proposed theoretical kinetic model on boron-doped diamond anodes is in excellent agreement with experimental results. In addition economic aspects of electrochemical organic mineralization are reported.

Electrolysis in aqueous 1 M HClO 4 and 1 M H 2 SO 4 solutions has been carried out under galvanostatic conditions using boron-doped diamond electrodes (BDD). Analyses of the oxidation products have shown that in 1 M HClO 4 the main reaction is oxygen evolution, while in H 2 SO 4 the main reaction is the formation of H 2 S 2 O 8. In both electrolytes small amounts of O 3 and H 2 O 2 are formed. Finally, a simplified mechanism involving hydroxyl radicals formed by water discharge has been proposed for water oxidation on boron-doped diamond anodes.
