γ-Radiolysis of gaseous hydrogen sulphide in the presence of hydrogen chloride, carbon disulphide and nitrous oxide

Abstract

Addition of HCl to H₂S increases the radiation yield of H₂G(H₂) 7.0→10.0 by an electron scavenging process involving HCl and H₂S. CS₂ lowers the H₂ yield in pure H₂S probably by reaction with hot H atoms and also scavenges the electrons in H₂S + HCl mixtures, lowering G(H₂) in the process to <7.0. Electron scavenging by addition of N₂O to H₂S to produce N₂ is shown to be a very complex system with surface reactions probably playing a part.
