Bio-FeMnOx integrated carbonaceous gas-diffusion cathode for the efficient degradation of ofloxacin by heterogeneous electro-Fenton process

Pharmaceutical Wastewater Remediation: A Review of Treatment Techniques

“…The heterogeneous process of EF by using a novel cathode made up of biogenic Fe−Mn oxide and carbon black was also carried out for removal of ofloxacin (OFL), an antibiotic drug which induces nauseatic symptoms and weakness in limbs of human beings from water and real livestock wastewater. 61 Optimum pH range was found to be between 3 to 8, and the removal decreased due to interferences from chloride ions due to active chlorine species. The cathode was stable and showed about 95% degradation kinetics as a constant degradation even after 10 cycles of usage.…”

“…The reduction in the toxicity and efficient removal of COD, total organic carbon (TOC), OFL, and UV 254 real wastewater were confirmed. 61 Use of iron-based MOF catalysts gave exemplary performance in 70 min of the trial run as explained in Table 4. This was due to dissociation of hydrogen peroxide at a fast rate, brought about by functionalization of the ligand as a result of changed active surface areas.…”

Unraveling the Degradation Mechanism and Interaction Mechanism of Ofloxacin Based on Reactive Oxygen Species via Electrochemically Activating Peroxymonosulfate

“…In addition, Cu 2 O@CuO nanowires as a PMS activator in the electroactive filter could also highly efficiently degrade OFN based on generated active oxygen . Then, bimetallic Fe–Mn oxides integrated carbonaceous as the gas-diffusion cathode for the heterogeneous electro-Fenton reaction could release the active radical ( • OH) for effective degradation of OFN . Ravneet et al reported that stable Ti/RuO 2 as the anode for OFN removal could achieve a high kinetic rate constant of 0.120 min –1 via generated • OH under electrochemical conditions.…”

These studies utilized the active species from the electrochemical reaction based on various electrodes effectively, which could efficiently degrade OFN along with a high kinetic rate.…”
