In the present work a study of oxidation of K4[Fe(CN)6] to K3[Fe(CN)6 under the treatment of posi- tive glow discharge of atmospheric pressure was carried out. The dependence of the K3[Fe(CN)]6 oxidation kinetics on its initial concentration and on the discharge current was studied as well as the influence of KCl addition as the catalyst of hydrogen peroxide decomposition and that of several alcohols as OH*-radicals ac- ceptors. Initial rates of K3[Fe(CN)]6 oxidation and yield-to-current values were obtained for different dis- charge currents. Oxidation reactions, initiated by OH*-radicals, were shown to take place in primary active zone of discharge only, and their rates would be limited by the transport of initial substances into the area of cathode spot and of interaction products out of it.
