Pulse radiolysis of Triton X-100 aqueous solution

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, including concentration effects is discussed. (author) 18 refs.; 3 figs
