Scholarcy highlights

  • Degradation rates increase with voltage, current density and electrolyte amounts
  • This paper aims to study the decolorization and degradation of textile dye Acid Blue 80 using indirect electrochemical oxidation on active platinum and non-active boron doped diamond anodes in the presence and formation of chloride ions
  • Following the decolorization of model wastewater, we monitored the subsequent degradation of Acid Blue 80 by repeatedly measuring the values of total organic carbon, total nitrogen, chemical oxygen demand and adsorbable organically bound halogens
  • After 24 h, Acid Blue 80 was mineralized by 90% at pH = 3.0 on the BDD anode, coupled with a 99% decrease in COD
  • The Pt anode showed a 94% decrease in chemical oxygen demand and 64% in total organic carbon
