Treatment of aqueous solutions of oxytetracycline by different electrochemical approaches: anodic oxidation, pressurized <scp>electro‐Fenton</scp> and oxidation by electrogenerated active chlorine

The tetracycline group (TCs) includes the most common antibiotics for treatment of both human and animal infections. TCs are resistant to biological degradation; hence, conventional wastewater treatments unable remove these contaminants. Here, utilization different electrochemical processes, such as electro-Fenton (EF), direct anodic oxidation (AO) indirect by electrogenerated active chlorine (EAC), aqueous solutions oxytetracycline (OTC), which is one TCs, was studied. effect various operating conditions evaluated optimize selected processes. EAC gave fastest abatement OTC, but lowest removal TOC formation chlorate. However, carbon felt cathodes allowed chlorate be reduced. AO highest removals, it required use an expensive anode, BDD, high cell potentials. EF performed with pressurized-air (5–10 bar) presented intermediate removals OTC respect consumed least energy. © 2023 Authors.
