In the present work a study of oxidation of K4[Fe(CN)6] to K3[Fe(CN)6 under the treatment of positive 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 -radicals acceptors. Initial rates of K3[Fe(CN)]6 oxidation and yield-to-current values were obtained for different discharge currents. Oxidation reactions, initiated by OH* addition as the catalyst of hydrogen peroxide decomposition and that of several alcohols as OH* 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. -radicals, were shown to take place in primary active
