摘要
In this study, in-situ electrogenerated persulfate (E-PS) was proposed as an alternative to the conventional addition of persulfate for advanced oxidation processes (AOPs) with facilitating conversion of co-existing Cu(II) to Cu(I) to degrade antibiotics without requiring any external supply of chemical additives. The degradation rate of sulfamethoxazole (SMX) by E/Cu(II)/Na2SO4 system (C0(Cu(II))=1 mM, C0(Na2SO4)=1 mM, E=25 V) was 93.3 % at t=90 min. Quenching combined with electron paramagnetic resonance (EPR) tests revealed that SO4 center dot-, center dot OH and Cu(III) were the primary contributors to SMX degradation. Solution pH, co-existing anions and organic matter affected the degradation performance of SMX. Four degradation pathways were proposed based on transformed products (TPs) determination, with pathways I and II being the dominant ones involving the cleavage of S-N bond in SMX. Ecological structure activity relationships (ECOSAR) program analysis implied that the TPs exhibited lower toxicity levels toward aquatic organisms compared to that of SMX. Additionally, the E/ Cu(II)/Na2SO4 system achieved decomposition rates over 80 % for various sulfonamides (SAs) and also demonstrated remarkable efficacy for SMX removal in different real waters, including tap water, lake water, river water and aquaculture wastewater, with all exceeding 80 % at t=90 min. E/Cu(II)/Na2SO4 system developed in this study had the potential to be a prospective technique for SAs purification due to its outstanding performance in degrading and detoxifying SAs.
