Effects of alkaline ferrocyanide on non-faradaic yields of anodic contact glow discharge electrolysis: Determination of the primary yield of OH . radicals

Abstract

Non faradaic yields of anodic contact glow discharge electrolysis (CGDE) originate through H . and OH . radical generated during the process. Scavenging effects of Fe(CN) 4-6 on OH . radicals, in alkaline media have been investigated. A kinetic analysis of the competing reactions of O - with different species in the system leads to an yield of 9.8 mol mol electron -1 of OH . and H . radicals each in the liquid phase reaction zone of anodic CGDE in good agreement with the yield reported from a study involving H . radical scavengers. © Springer Science+Business Media, LLC 2011.
