Insights into the electrochemical degradation of sulfamethoxazole and its metabolite by Ti/SnO2-Sb/Er-PbO2 anode

Electrochemical degradation of sulfamethoxazole (SMX) and its metabolite acetyl-sulfamethoxazole (Ac-SMX) by Ti/SnO2-Sb/Er-PbO2 were investigated. Results indicated that the electrochemical degradation of SMX and Ac-SMX followed pseu

A simple Fe3+/bisulfite system for rapid degradation of sulfamethoxazole

Sulfate radical (SO4-) based oxidation technologies have been widely used in the remediation of antibiotic-containing wastewater. Activated persulfates are efficient reagents for achieving SO4-, but the storage and transportation of concentrated persulfates present associated safety issues. In this study, bisulfite (BS) was used as an alternative precursor for replacing persulfates, and a simple advanced oxidation system (Fe3+/BS) for generating SO4- and hydroxyl radical (HO) was formulated and evaluated for removing sulfamethoxazole (SMX) from contaminated water. The initial pH, dosages of Fe3+ and BS, as well as the water matrix were investigated to improve the SMX degradation. The results indicated that 1 μmol L-1 SMX was completely removed within 5 min at optimum initial pH of 4.0, Fe3+ dosage of 10 μmol L-1, BS dosage of 100 μmol L-1 and temperature of 25 °C. The presence of HCO3- and natural organic matter (NOM) showed obviously negative effects on SMX degradation, while Cu2+ could slightly promote the degradation of SMX if its concentration was in an appropriate range (～1 μmol L-1). Scavenger quenching experiments confirmed the presence of SO4- and HO, which resulted in efficient SMX degradation in the Fe3+/BS system. During the radical chain reactions, Fe2+ and Fe3+ could be converted into each other to form self-circulation in this system. The degradation pathway of SMX by Fe3+/BS was proposed including hydroxylation and bond cleavage.
