Pulse radiolysis of deaerated aqueous solutions of 4·10–5–2.4·10–3 mol dm–3 Triton X-100 gives rise to a transient species originating from the reactions of OH radicals and H atoms. The rate constants of these reactions were found to be 8.8·109 mol–1·dm3·s–1 and 1.25·109 mol–1·dm3·s–1, respectively, for Triton X-100 concentrations below CMC. The corresponding transient species were found to decay according to second order kinetics. The mechanism of the reactions involved including concentration effects is discussed.
