Constructing Hollow Multishelled Microreactors with a Nanoconfined Microenvironment for Ofloxacin Degradation through Peroxymonosulfate Activation: Evolution of High-Valence Cobalt-Oxo Species

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(42), P. 16141 - 16151

This study constructed hollow multishelled microreactors with a nanoconfined microenvironment for degrading ofloxacin (OFX) through peroxymonosulfate (PMS) activation in Fenton-like advanced oxidation processes (AOPs), resulting adequate contaminant mineralization. Among the microreactors, triple-shelled Co-based microsphere (TS-Co/HM) exhibited optimal performance; its OFX degradation rate was 0.598 min-1, which higher than that of Co3O4 nanoparticles by 8.97-fold. The structural tuning Co/HM promoted formation oxygen vacancies (VO), then facilitated evolution high-valence cobalt-oxo (Co(IV)═O) and shifted entire t2g orbital Co atom upward, promoting catalytic reactions. Co(IV)═O identified using phenylmethyl sulfoxide (PMSO) probe situ Raman spectroscopy, theoretical calculations were conducted to identify lower energy barrier on defect-rich catalyst. Furthermore, TS-Co/HM catalyst remarkable stability inorganic (Cl-, H2PO4-, NO3-), organic (humic acid), real water samples (tap water, river hospital water), continuous flow system microreactor. could enrich reactants cavities, prolong residence time molecules, increase utilization efficiency Co(IV)═O. work describes an process involving contaminants elimination. Our results may encourage use structures inform design catalysts AOPs.

Antibiotics removal from aquaculture effluents by ozonation: chemical and toxicity descriptors

Water Research, Journal Year: 2022, Volume and Issue: 218, P. 118497 - 118497

Published: April 25, 2022

Antibiotics are often applied in aquaculture to prevent fish diseases. These substances can cause disturbances on receiving waters, when not properly eliminated from the effluents. In this work, ozone (O3) was investigated as a possible oxidizing agent remove fishery antibiotics effluents: florfenicol (FF), oxytetracycline (OTC), sulfadimethoxine (SDM), sulfamethoxazole (SMX), and trimethoprim (TMP). Batch experiments were performed using ultrapure water effluents spiked with mixture of target at relatively high concentrations (10 mg L-1 each). OTC, SMX TMP fully removed (< 30 min) regardless tested conditions, mainly by O3 direct attack. contrast, FF partially min (∼ 10 60%, water, respectively), but only presence hydroxyl radicals (HO•), reaching levels below detection limits after 60 min. case SDM, its degradation highly influenced selected matrix, removals always higher than 68%. continuous-flow applying more environmentally relevant antibiotic (100 ng each) low doses (1.5 L-1), ozonation (> 98%) all hydraulic retention time (HRT) min, except (68%). Although by-products detected treated samples, zebrafish (Danio rerio) embryotoxicity tests did show toxicity increase treatment. Ozonation is thus solution Still, full-scale studies farms needed, generation HO• may be favoured readily oxidize antibiotic.
