同海大学 Tongji University I.Ozone Chemistry Some of the chemical properties displayed by ozone may be described by its decomposition reaction,which are proceed as following: O3+H20→HO3+OH (11-35) HO3+OH→2HO2 (11-36) 03+H02→H0+20, (11-37) H0+H02→H2O+O2 (11-38)

同海大学 Tongji University The free radicals formed,H0,and HO,have great oxidizing powers,and are probab/y the active form in the disinfection process. These free radicals also possess the oxidizing power to react with other impurities in aqueous solution. (refractory organics,such as pesticides,algae)
