Rate constants of reactions of ozone with organic and inorganic compounds in water. 3. Inorganic compounds and radicals

Second-order rate constants for reactions of ozone with 40 inorganic aqueous solutes are reported. Included are compounds of sulfur, chlorine, bromine, nitrogen, and oxygen, as well as free radicals. Most of these compounds exhibit an increase in rate constant with increasing pH corresponding to the...

Description
Summary:Second-order rate constants for reactions of ozone with 40 inorganic aqueous solutes are reported. Included are compounds of sulfur, chlorine, bromine, nitrogen, and oxygen, as well as free radicals. Most of these compounds exhibit an increase in rate constant with increasing pH corresponding to their degree of dissociation. Rate constants are based on ozone consumption rates measured by conventional batch-type or continuous-flow methods and determinations of stoichiometric factors. Also listed are data determined by pulse-radiation techniques using kinetic spectroscopy. Additional literature data are reviewed for completeness. Results are discussed with respect to water treatment and environmental processes.
