Antimony-doped tin dioxide ceramics used as standalone membrane electrodes in electrofiltration reactors enhance the oxidation of organic micropollutants

In the present work, microporous ceramics made of antimony-doped tin dioxide produced using a facile synthesis procedure were evaluated during degradation norfloxacin in novel electrofiltration process. The used as standalone electrodes accomplishing dual function: anodes and microfiltration membranes. simultaneous generation hydroxyl radicals permeation electrolyte through ceramic favors effective utilization their high active area organic compounds. progress process was compared with that conventional flow electrolysis reactor boron-doped diamond. By changing from to an configuration, generated is evidenced by delayed transition electrochemical-to mass transfer-controlled rates. Evaluation intermediate by-product concentrations confirms formation acetate ions prior stage mineralization pathway both types electrodes. After 4 h electrolysis, rates 98.3% degrees 82% attained at highest permeate 60 mL min−1, approaching outstanding performance commercial diamond
