Dual roles of hydroxyl radicals and effects of competition on ozonation kinetics of two phenazone-type pollutants

open access: yesEmerging Contaminants, 2015
Ozonation has been proved to be a promising approach for eliminating emerging pollutants in wastewater. In previous studies, emerging pollutants including diverse pharmaceuticals were found to exhibit significantly different ozonation reactivity. However,

Ozone and Ozonated Oils in Skin Diseases: A Review

open access: yesMediators of Inflammation, 2010
Although orthodox medicine has provided a variety of topical anti-infective agents, some of them have become scarcely effective owing to antibiotic- and chemotherapeutic-resistant pathogens. For more than a century, ozone has been known to be an excellent disinfectant that nevertheless had to be used with caution for its oxidizing properties.

Surrogates for the removal by ozonation of the cytotoxicity and DNA double-strand break effects of wastewater on mammalian cells

open access: yesEnvironment International, 2020
Effluents from wastewater treatment plants (WWTPs) may contain various pollutants with potential toxic effects. Ozonation is widely applied to purify wastewater, which may influence the toxicity and water quality indices simultaneously.

Degradation Characteristics of Aniline with Ozonation and Subsequent Treatment Analysis

open access: yesJournal of Chemistry, 2015
Owing to the toxicity and low biodegradability of aniline in water, its removal usually needs high cost processes such as adsorption and advanced oxidation. The degradation characteristics of aniline during ozonation were studied.
