Electrochemical treatment of wastewaters containing organic pollutants on boron-doped diamond electrodes: Prediction of specific energy consumption and required electrode area

A theoretical analysis is presented for the prediction of the specific ener gy consumption and the required electrode surface for the electrochemical c ombustion of organic compounds on synthetic boron-doped diamond (BDD) thin film electrodes. The model is formulated for a perfect mixed electrochemica l reactor operated as a batch recirculation system under galvanostatic cond itions. The anodic oxidation of organics is assumed to be under diffusion c ontrol. An experimental validation with the anodic oxidation of phenol and under different experimental conditions is also provided. (C) 2001 Elsevier Science B.V. All rights reserved.
