Mediated electrochemical oxidation (MEO) is emerging field towards environmental pollutant removal process using anodic part of a full electrochemical cell. At the same time, Mediated electrochemical reduction (MER) is in initial level. The present investigation focuses on reduction of Ni(II)(CN)53- especially at the Ag electrode in different temperatures. At a first step, current density, Pt electrode as anode in 5 M H2SO4 in anodic, and 0.01 M CoSO4 mediator kept constant. The Ni(II)(CN)53- reduction investigated using its different temperatures like 10, 20, and 50 C at Ag cathode in 10 M KOH solution. The reduction of Ni(II)(CN)53- confirmed via ORP electrode by reduction potential variation. The reduction efficiency changes calculated using titration with KMnO4 |
