Abstract
Solutions of H2O216,16 in water highly enriched in O18 were irradiated with x rays and protons. The effects of H2O2 concentration, pH, bromide and nitrite ions, on the yield of the isotopic species H2O216,18 and H2O218,18, were investigated. The ``molecular'' H2O2 is formed with a G value of 0.3 in neutral solutions. The formation of H2O216,18 is attributed to the attack of O18H radicals on H2O216,16. The evolved O216,18 may be regarded as a product of a parallel reaction. The yield of O216,18 is dependent on an exchange reaction between HO2 and H2O2. Specific effects due to added NO2— and high concentrations of Br— are discussed.Keywords
