Scholarcy highlights

  • The mineralization of ketoprofen by anodic oxidation was studied by employing boron doped diamond and Pt electrodes
  • The redox behavior of KP molecule, fouling of electrodes, generation of oxygen and active chlorine species were studied by cyclic voltammetry
  • The degradation and mineralization were monitored by UV–vis spectrophotometer and total organic carbon analyzer, respectively
  • The results were explained in terms of in situ generation of hydroxyl radical, peroxodisulfate, and active chlorine species
  • The physisorbed OH on BDD was observed to trigger the combustion of KP in to CO2 and H2O
  • The poor mineralization at both BDD and Pt anodes in the presence of NaCl as supporting electrolyte was ascribed to the formation of chlorinated organic compounds which are refractory
  • Complete mineralization of KP molecule was achieved using Na2SO4 as supporting electrolyte
