Abstract
The initial yields of H2O2 in aerated water, G(H2O2) super O2, and in water containing H2 and O2, G(H2O2) super H2,O2, have been measured for alkaline solutions irradiated with 60Co gamma-rays. A reaction mechanism in accordance with the observed results and the literature values of the rate constants of likely radical reactions has been developed. It is assumed that in the alkaline solutions investigated OH radicals react with OH(-) ions to form O(-) radicals which react preferentially with O2 to form O3(-) radicals which then react either with H2 or H2O2. The increase in G(H2O2) super H2,O2 at pH 12 is attributed to a difference in the rate of reaction of O3(-) with H2O2 and HO2(-), k(O3(-) + H2O2)/k(O3(-) + HO2(-) = 2.45.
