Abstract

The photochemistry of basic aqueous solutions containing hydrogen peroxide and oxygen has been investigated by the flash photolysis method. The decay of O₃⁻ was followed at 4300 Å over the pH range 13 – 13.7 as a function of hydrogen peroxide and oxygen concentrations. The decay was found to be of the first order under all conditions −[d(O₃)⁻/dt] = k_obs[O₃⁻]. The pseudo first‐order rate constant k^obs was found to be dependent on H₂O₂ and O₂ concentrations. A mechanism which is consistent with the experimental results is suggested.
