Abstract
Section titled āAbstractāThe electrochemical oxidation of vanillic acid (4-hydroxy-3-methoxybenzoic acid), one of the most representative phenolic type \ncompounds present in olive oil mill wastewater, was studied by galvanostatic electrolysis using boron-doped diamond (BDD) as \nanode. The influence of several operating parameters, such as applied current density, initial vanillic acid concentration, temperature \nand initial pH value was investigated. Measurements of Chemical Oxygen Demand (COD) were used to follow the oxidation. The \nexperimental data indicated that the COD removal follows a pseudo first-order kinetics and the apparent rate constant increased with \nthe applied current and temperature and decreased with pH and organic concentration
