Title: Radiolytic yields G(HNO2) and G(H2O2) in the aqueous nitric acid system
Abstract: Abstract The gamma radiolysis of aqueous nitric acid has been investigated in presence of sulphanilamide (SA) as a function of dose, and of nitric acid and SA concentrations. Both G (HNO 2 ) and G (H 2 O 2 ) values were determined at different concentrations of nitric acid in the presence of 0·02 mol dm −3 SA. It has been shown that SA reacts with OH radicals and with hydrated electrons [ k ( e aq - +SA) = 3·5 × 10 9 dm 3 mol −1 s −1 ] without affecting G (HNO 2 ) in the present system. The G (HNO 2 ) value increases with increase of nitric acid concentration up to 8 mol dm −3 , whereas G (H 2 O 2 ) remains nearly unaffected. The results are discussed.
