A comparative study of the electrochemical oxidation of the herbicide tebuthiuron using boron-doped diamond electrodes

► The concentration of TBH was reduced by 90% following electrolysis with BDD/Ti. ► Electrolysis with BDD/Ti electrodes led to the removal of 80% of total organic carbon. ► The reduction and formation of the byproducts of TBH could be monitored by HPLC. ► Ion chromatography confirmed that the electrochemical breakdown of TBH with BDD/Ti. ► The least doped BDD was the more efficient.
