Non faradaic yields of anodic contact glow discharge electrolysis (CGDE) originate through H-center dot and OH center dot radical generated during the process. Scavenging effects of Fe(CN) (6) (4-) on OH center dot 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 center dot and H-center dot radicals each in the liquid phase reaction zone of anodic CGDE in good agreement with the yield reported from a study involving H-center dot radical scavengers.
