The Radiolysis of Aqueous Ammonium Cyanide: Compounds of Interest to Chemical Evolution Studies

The Radiolysis of Aqueous Ammonium Cyanide:Compounds of Interest to Chemical Evolution Studies Oxygen-free aqueous solutions of NH4CN (0.1 M, pH 9) were exposed to gamma rays from a 60Co source, the mixture of nonvolatile products was fractionated, and the fractions were analyzed. The procedures were chosen to make effective investigations of radiolytic products, and to minimize the contributions of chemical…

Radiolysis of aqueous solutions of ammonium bicarbonate over a large dose range

Oxygen-free aqueous solutions of 0.05 mol dm-3 ammonium and sodium bicarbonate were studied after receiving various doses of 60Co gammas (0.01–400 kGy) or 0.5–20 Gy pulses of 10 Mev electrons. Formate and oxalate were found to be the main radiolytic products, in addition to trace amounts of formaldehyde and an unidentified polymer. A large initial yield of formate in the γ-radiolysis, G(HCOO–)=2.2, is…
