20.500.12556/DiRROS-21453 Vacuum ultraviolet radiation from gaseous plasma for destruction of water contaminants Innovative technological solutions are needed for water decontamination to combat the diverse pollutants present in water systems, as no single optimal decontamination technique is appropriate for all circumstances. Vacuum-ultraviolet (V-UV) radiation is a source of energetic photons that break molecular bonds, producing a plethora of chemically reactive agents, most notably OH● radicals, which can cause the degradation of harmful pollutants. Low-pressure gaseous plasma is a good source of V-UV radiation; however, its application to liquid water poses challenges. We constructed an inductively coupled radiofrequency plasma to produce high-intensity V-UV radiation, which was applied to contaminated water via a V-UV-transparent window. Plasma was sustained in hydrogen, as it produces the highest V-UV intensity among all gases at selected discharge parameters. Bacteriophage MS2 was used as an indicator of microbial decontamination efficiency. Reactive oxygen and nitrogen species were measured at various treatment setups to quantify their effect on MS2 inactivation and elucidate the primary inactivation factors. At optimal conditions, the concentration of active virus dropped by 9 log10 PFU/mL in 60 s. The optimal experimental setup was then used to treat bacteria E. coli, S. aureus, antibiotic tetracycline, and synthetic dye methylene blue as representatives of other types of pollutants, all of which were effectively removed/degraded within 10 min of treatment. A comparison of energy efficiency (EEO) to other disinfection setups was made for bacteriophage inactivation. With a low EEO value, we showcase the potential of this technique for further work in this field. water treatment radical obdelava vode čiščenje vode radikali true false true Elsevier Nizozemska Angleški jezik Slovenski jezik © 2025 The Authors Neznano 2025-02-07 12:49:14 2025-02-07 12:49:15 2025-02-08 03:35:28 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Soavtorji: Rok Zaplotnik, Miran Mozetič, Alenka Vesel, Arijana Filipić, David Dobnik, Belisa Alcantara Marinho, Gregor Primc; Opis vira z dne 7. 2. 202; str. 1-12 Vol. 375, [article no.] 124396 Feb. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 2024-10-26 2025-01-29 2025-02-01 533 0301-4797 10.1016/j.jenvman.2025.124396 225452803 https://www.sciencedirect.com/science/article/pii/S030147972500372X 1 8f3eb5ad-e549-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30593 RAZ_Zver_Mark_2025.pdf RAZ_Zver_Mark_2025.pdf 1 6082D26C91548876CC96A86BF698337C 6ea7416dab6373b4fe9224f6e517ac02922c61160cd7abc655e7656488f4d9fa fbee30f8-e54a-11ef-9f1e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30594 Institut Jožef Stefan 0 0 0
