TY  - JOUR
AB  - Boron-doped diamond (BDD) electrodes have the greatest known oxygen overpotential range; a characteristic that has allowed the material to be well suited for electro-oxidation processes in aqueous media. When operating in a potential range of water decomposition, strongly oxidising hydroxyl radicals are formed while oxygen evolution is minimised. The majority of research studies undertaken to-date have focused on the application of BDDs for the remediation of wastewater contaminants, however there is an increasing need for a suitable technology to address recalcitrant micropollutants in a drinking water context. Pesticide micropollutants are widely detected in surface- and ground-waters and are of increasing concern. In this paper, the treatment of pesticides by BDD electro-oxidation is reviewed. Their degradation and mineralisation, as well as the effect of operating conditions, formation of intermediate by-products, reaction pathways and kinetics are summarized. In general, BDD electro-oxidation was found to be effective for the degradation of pesticides with the degradation performance proportional to the electrolytic current, due principally to the increased generation of OH radicals. Most contaminants followed pseudo first-order reaction kinetics under mass transport limitations. Generally, the same aromatic and aliphatic by-products were formed through similar oxidation pathways. Finally, research gaps and potential future research topics are discussed.
