Abstract
Section titled āAbstractāThis paper deals with the degradation of diclofenac by electrochemical oxidation in NaClO4 medium at neutral pH using a FM01-LC reactor equipped with a boron doped diamond electrode (BDD). Microelectrolysis studies were carried out to find the current density domain where hydroxyl radical (ā¢OH) formation is favored, 10 ā¤ j ā¤ 20 mA cm-2. Electrolysis experiments at mean linear flow velocities of 14.6 ā¤ u ā¤ 58.4 cm s-1 were performed. The experimental set-up achieved 100% diclofenac mineralization with 78% current efficiency and energy consumption of 2.54 kWh m-3 at j = 15 mA cm-2 and u=29.2 cm s-1.
