22 de mar. de 2024 · Switching the UV radiation wavelength from 254 to 222 nm promotes the radical generation in the UV/peroxydisulfate AOP and enhances micropollutant degradation. Far-UVC Photolysis of Peroxydisulfate for Micropollutant Degradation in Water | Environmental Science & Technology
3 de ene. de 2022 · Ultraviolet (UV)-based advanced oxidation processes (AOPs) are increasingly used for the degradation of micropollutants in water and wastewater. This study reports a novel UVA/chlorine dioxide (ClO 2 ) AOP based on the photolysis of ClO 2 using energy-efficient UV radiation sources in the UVA range (e.g., UVA-LEDs).
13 de ene. de 2022 · A High-Radical-Yield Advanced Oxidation Process Coupling Far-UVC Radiation with Chlorinated Cyanurates for Micropollutant Degradation in Water. Environmental Science & Technology 2023, 57 (47) , 18867-18876. https://doi.org/10.1021/acs.est.3c00255
5 de feb. de 2024 · A systematic review of the degradation of organic UV filters (OUVFs) in various water environments was conducted, for the first time, to provide an overview on the associated reaction mechanisms and their byproducts through a meta-analysis.
1 de ago. de 2022 · Micropollutant degradation by UV/H 2 O 2 in drinking water: Facilitated prediction through combination of model simulation and portable measurement
1 de nov. de 2023 · We studied the impact of environmentally relevant UV and temperature (37 °C) weathering of four high-production volume plastics (polystyrene, polypropylene, low-density polyethylene, and high-density polyethylene) suspended in water.
30 de jun. de 2022 · Chloride in water had a negligible effect on iopromide degradation, whereas bromide inhibited iopromide degradation in the UV/Cl 2 system. The contributions of UV irradiation, •OH, and RCS to iopromide degradation during UV/Cl 2 treatment were calculated as 20.8%, 54.1%, and 25.1%, respectively.
