Stability of ozone in aqueous solution

The decomposition rate, measured in the presence of excess radical scavengers is expressed by a pseudo first-order kinetic equation of the following equation 1 (Bruno L. etal., 1991) [Pg.10]

The pseudo first-order constant is linear function of pH, this evolution reflects the fact [Pg.10]

Ozone decomposition occurs in alkaline aqueous solution that can be represented by the following fundamental reactions [Pg.11]

The hydroxyl radical ( OH) generation from decomposition of ozone in alkaline pH mainly depends on the hydroperoxide free-radical initiating step (rate-determining step) in the chain reaction and the regeneration of the superoxide radical ion Oi [Pg.11]
