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 decomposition [PDF]

open access: yesInterdisciplinary Toxicology, 2014
ABSTRACT Catalytic ozone decomposition is of great significance because ozone is a toxic substance commonly found or generated in human environments (aircraft cabins, offices with photocopiers, laser printers, sterilizers). Considerable work has been done on ozone decomposition reported in the literature.
