Metal ions mediated electrochemical reduction (MER) is in initial level, which must be enrooted to utilize the full electrolytic cell. Metal complexes are more suitable to use as a mediator in the MER process due to stabilize the active low valent state of metal ion. 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 meidator kept constant. Electrolytic reduction of Ni(II)(CN)53- investigated using its different electrodes like Ag, Ti, carbon, and Cu in 10 M KOH solution. The reduction of Ni(II)(CN)53- confirmed via ORP electrode by reduction potential variation. The reduction efficiencies changes calculated using titration with KMnO4. Cyclic voltammetry analysis at said electrodes corelated with the reduction of Ni(II)(CN)53-. A model pollutant dichloromethane degradation done and confirmed by FTIR and HACH analysis |
