Abstract
Absolute rate constants for the reaction of the hydrated electron and hydroxyl radical with ozone in aqueous solution have been determined by using pulse radiolysis techniques. The rate constant, k(eaq- + O3) = (3.60 ± 0.14) × 1010 dm3 mol-1 s-1, was measured in the pH range 4.1-6.05 by following the decay of eaq- at 600 nm. The rate constant k(OH• + O3) = (3.02 ± 0.25) × 109 dm3 mol-1 s-1, was obtained by a competition method at pH 6.7 with acetate ions as the OH• radical scavengers. The ozone concentration for both studies varied from 0.05 × 10-3 to 0.50 × 10-3 mol dm-3.
