title: Electrochemical oxidation of phenolic and other organic compounds at boron doped diamond electrodes for wastewater treatment: effect of mass transfer.
abstract: The paper presents the results of an experimental study on oxidation at boron doped diamond electrodes (BDD) of some phenolic compounds: phenol (PH), para-hydroxibenzoic acid (PHB), cathecole (CT), hydroquinone (HQ) are considered, singularly contained in aqueous solutions or in the presence of glucose (G), which was selected to represent the class of biodegradable compounds. Oxidation of benzoquinone (BQ) and maleic acid (MA), generally detected as intermediates products from phenol degradation, is also investigated. Great attention is paid to verify the feasibility of a selective process in which the oxidation is specifically addressed to the phenolic fraction up to non toxic intermediate products which are more biodegradable than the original phenols.
