Efficient degradation of chloroquine drug by electro-Fenton oxidation: Effects of operating conditions and degradation mechanism.

ABSTRACT: In this work, the degradation of chloroquine (CLQ), an antiviral and antimalarial drug, using electro-Fenton oxidation was investigated. Due to the importance of hydrogen peroxide (H₂O₂) generation during electro-Fenton oxidation, effects of pH, current density, molecular oxygen (O₂) flow rate, and anode material on H₂O₂ generation were evaluated. H₂O₂ generation was enhanced by increasing the current density up to 60 mA/cm² and the O₂ flow rate up to 80 mL/min at pH 3.0 and using carbon felt cathode and boron-doped diamond (BDD) anode. Electro-Fenton-BDD oxidation achieved the total CLQ depletion and 92% total organic carbon (TOC) removal. Electro-Fenton-BDD oxidation was more effective than
