The ozonation effect on flocculation and polymer consumption reduction in the hybrid treatment of Iran Central iron ore companies' effluent: a cost–benefit study

open access: yesApplied Water Science, 2022
Iran's most important iron ore mine is located in the central region, and because of the water shortage in this area, the need to reuse the effluent from this mine is essential.

Formation and estimated cytotoxicity of trihalomethanes and haloacetic acids during ozonation of nonylphenol in bromide-containing water after chlorination process: Impact of ozonation initial pH

open access: yesToxicology Reports
The presence of nonylphenol (NP) in bromide-containing water contributed to the formation of regulated disinfection by-products (DBPs): trihalomethanes-4 (THM4) and haloacetic acids-5 (HAA5).

Catalytic ozonation mechanism over M1-N3C1 active sites

open access: yesNature Communications, 2023
The structure-activity relationship in catalytic ozonation remains unclear, hindering the understanding of activity origins. Here, we report activity trends in catalytic ozonation using a series of single-atom catalysts with well-defined M1-N3C1 (M ...

Enhancing nanoplastics removal by metal ion-catalyzed ozonation

open access: yesChemical Engineering Journal Advances
Nanoplastics (NPs), characterized by sizes < 1 µm, are not completely removed in conventional drinking water treatment plants affecting human health. Catalytic ozonation appears as a promising alternative due to its ability to oxidize emerging pollutants

Weak Acids Enhance Halogen Activation on Atmospheric Water’s Surfaces [PDF]

open access: yes, 2011
We report that rates of I_2(g) emissions, measured via cavity ring-down spectroscopy, during the heterogeneous ozonation of interfacial iodide: I^–(surface, s) + O_3(g) + H+(s) →→ I_2(g), are enhanced several-fold, whereas those of IO·(g) are unaffected,

Stratospheric ozone depletion [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 1991
Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation.

OZONE GENERATOR AND OZONE GENERATION

open access: yesJournal of Amasya University the Institute of Sciences and Technology, 2021
Because ozone is a very active oxidizing agent and powerful antimicrobial property, it has found use in many areas. It has long been used in dentistry, in medical laboratories, in cleaning up chemical waste mixed with hospital sewage, in extending the shelf life of food through ozonation, in cleaning urban drinking water, in raising pools and fish ...

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

open access: yesAdvanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...
