Radiolysis of Fremy's Salt in the Presence of Some Hydrated Electron Scavengers in Alkaline Aqueous Solution

Abstract

AbstractFremy's salt, ON(SO3)22−, was irradiated with γ‐rays in deaerated alkaline aqueous solutions in the presence of NO3−, N2O. In the presence of N2O an increase of the G(‐ON(SO3)22− = G from 6.1 to about 6.7 was observed within a limited range of concentration, while with NO3− the change is gradual. This is consistent with NO2 and OH produced, respectively, in the reaction of eaq− with Fremy's salt, taking place in one‐electron‐equivalent processes, and with the assumption that pairs of radicals may originate from water molecules.
