Abstract

Reduction of nitrate to nitrite takes place when the stored energy in the form of colour centres is released during dissolution of γ-irradiated NaCl crystals in aqueous sodium nitrate solution. Various parameters like dose, amount, storage time and particle size of irradiated NaCl salt which control the yield of nitrite have been studied. Similarly, the effect of concentration of NaNO3 and the role of precipitation on the yields of nitrite in aqueous TlNO3 and AgNO3 have been investigated. The energy transfer parameter has been determined as the ratio of G/NO −2 / obtained by the addition of irradiated NaCl to that of direct γ-radiolysis. The data permit the evaluation of the concentration of colour centres in the irradiated NaCl crystals on the basis of the mechanism of reduction of nitrate.
