Effect of cyanide additive on the radiolytic decomposition of sodium and potassium nitrates

Conference:

Abstract

Gamma ray induced decomposition of NaNO{sub 3} and KNO{sub 3} in presence of 90-99.5 mol% of NaCN and KCN has been studied at different absorbed doses up to 250 kGy. [NO{sub 2}{sup -}] varied with the concentration of the cyanide additive and absorbed dose. G(NO{sub 2}{sup -}) values calculated on the basis of electron fraction of the nitrate salt are enhanced by 2-4 orders of magnitude compared to pure nitrate salt. It is proposed that radical species of nitrate may interact with the colour/radical species of cyanide by energy transfer so as to enhance G-value. Nature of cation and absorbed dose also play an important role. (author). 6 refs., 1 tab., 2 figs.
