Effect of nitrate ions on the oxidation of iodide ions during the dissolution of γ-irradiated NaCl in aqueous binary mixture of iodide and nitrate

Abstract

It is now well established that the oxidation of iodide ions and the reduction of nitrate ions take place when γ-irradiated sodium chloride is dissolved in aqueous iodide and nitrate solutions, respectively. The yield of iodine decreases and that of nitrite increases with increasing concentration of nitrate in a binary mixture of iodide and nitrate when the irradiated salt is dissolved in it. The results are explained on the basis of the reactions of colour centres with iodide and nitrate ions present in the binary mixture.
