“…(2) with and [16]. is thought to be rather unreactive towards most inorganic and organic substrates and reaction (11) was postulated to be the only route by which (as ) can react with non radical solutes [5,22,23]. Assuming that this is also the case under our experimental conditions, the decay rate of can be written as in eq.…”

“…Several species, mainly and , contribute to the absorption curves obtained at 260 nm. Even though O 3 is postulated to be formed through reaction of and (reaction (18) in Table II) [5], its concentration does not affect the absorbance at 260 nm within the experimental error. The simulated time profiles for these species (Fig.…”

The photolysis of strong alkaline solutions of H 2 O 2 yields , which in the presence of molecular oxygen forms the ozonide radical ion,. A detailed kinetic study on the reaction mechanisms involved during formation and decay of radical ions in these solutions, in the presence and absence of added scavengers is reported. In order to obtain a complete interpretation of the experimental data, kinetic computer simulations were done using a complete set of reactions. A very good agreement between experimental and computer simulated data is obtained. The following simplified mechanism accounts for the observed first-order decay of in alkaline hydrogen peroxide solutions:with S: scavengers.

This article discusses solubility, absorptivity, explosivity, as well as thermodynamic, spectral, structural, and other physical properties of ozone in the gaseous, liquid, and solid states; it reviews both organic and inorganic chemistry and offers various analytical methods for determining ozone in the solution and the gas phase. It examines, from a mechanistic viewpoint, not only the thermal and photochemical decomposition of gaseous and aqueous ozone, but also its generation, including gas preparation, electrical requirements and characteristics, efficiency, costs, and design. In addition, the article investigates atmospheric ozone formation in the troposphere and the stratosphere from the standpoint of photochemical smog, surveying the effect of natural and anthropogenic contaminants on ozone decomposition. Finally, the article considers numerous health and safety issues, including such topics as the depletion of ozone layer, environmental and human exposure, and ozone disinfection by‐products. Ozone can be used in drinking water, high purity water for bottling and canning plants, as well as the pharmaceutical and electronics industry; it can be used to bleach textiles and natural products, to control industrial wastewater pollution and sewage, to disinfect wastewater as well as water for large aquariums and shrimp hatcheries, to treat process water, swimming pools, and spas; it can also be used for pulp bleaching, organic synthesis, medical applications, and food preservation.
