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) 6 4− 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.

Keywords
