Photocatalytic Removal of the Antibiotic Furazolidone Using g-C3N4 in the Presence of Persulfates Under Lab and Pilot Scale Conditions

Water, Journal Year: 2025, Volume and Issue: 17(4), P. 602 - 602

Furazolidone, a nitrofuran antibiotic, has been broadly used in aquaculture and veterinary medicine, its presence water poses considerable environmental health hazards due to toxicity. This study investigated hybrid photocatalytic process for the removal of furazolidone, employing graphitic carbon nitride (g-C3N4) persulfate anions (PS) under both laboratory pilot-scale conditions. The synergistic effect g-C3N4 PS enhanced generation reactive species, facilitating efficient degradation FZ two different aqueous matrices. Through scavenging studies, positive holes were determined be dominant followed by sulfate radicals. Seven transformation products tentatively identified via UHPLC-LTQ/Orbitrap MS analysis. optimized system (g-C3N4/PS) achieved 100% furazolidone less than 60 min simulated solar light, demonstrating potential large-scale application wastewater remediation. Furthermore, experiments using real secondary treated municipal proved that applied is capable achieving an 86.2% (k = 0.017 min−1) as well 90% decrease effluent ecotoxicity within 120 UVA irradiation. provides insights into sustainable processes antibiotic contaminants from underscores role g-C3N4-based approaches upper-scale applications.

Hierarchical WS2-WO3 Nanohybrids with Flower-like p-n Heterostructures for Trimethylamine Detection

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(16), P. 1322 - 1322

Published: Aug. 6, 2024

The detection of trimethylamine (TMA) is critically important due to its toxic and flammable nature, which poses significant risks human health the environment. However, achieving high response, rapid kinetics, selectivity, low operating temperatures in TMA sensing remains challenging. In this study, WS2/WO3 nanohybrids with flower-like hierarchical structures were synthesized via an situ sulfurization process, utilizing varying amounts thioacetamide control state WO3. These novel exhibit remarkable selectivity towards TMA, as well response recovery characteristics. Specially, optimal sensor, composed 5% nanohybrids, demonstrates exceptional performance, including a (19.45 at 10 ppm), good repeatability, reliable long-term stability, theoretical limit (15.96 ppb). superior capabilities are attributed formation p-n heterojunctions interface, unique structures, catalytic activity WS2. Overall, work provides straightforward versatile approach for synthesizing multifunctional nanomaterials by combining metal oxide micro-flowers transition dichalcogenide nanoflakes applications monitoring complex environments.
