Abstract
The formation of hydrogen peroxide in bidistilled water under the influence of UV-C radiation from a DKB-9 low-pressure mercury lamp has been studied. The yield of hydrogen peroxide was (1 ± 0.2) × 10−7 mol (L s)−1. The wavelengths of radiation under the influence of which the formation of H2O2 is possible have been estimated. It has been assumed that the intermediate product of the reaction is the HO2./O2.-radical. To identify it, oxidation–reduction reactions in aqueous solutions containing Fe2+, Fe3+, and I− ions at pH values from 0.8 to 8.1 have been studied. The quantum yield of HO2. radicals in an acidic medium under the influence of radiation from the mercury lamp is 0.015 ± 0.005.
