Notes:
The photolysis of strong alkaline (pH〉12.7) solutions of H2O2 yields O·-, which in the presence of molecular oxygen forms the ozonide radical ion, O3·-. A detailed kinetic study on the reaction mechanisms involved during formation and decay of O3·- radical ions in these solutions, in the presence and absence of added O·-/HO· 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 O3·- in alkaline hydrogen peroxide solutions:O·- + O2 → O3·-O3·- → O·- + O2O·- + S →OH· + S →HO· + HO2- → O2·- + H2OO·- + HO2- → O2·- + HO-With S: O·-/HO· scavengers. © 1997 John Wiley & Sons, Inc.
