MEO is emerging field towards environmental pollutants removal process using anodic part of a full electrochemical cell. At the same time, MER is in initial level, which must be developed to utilize the full electrochemical cell. It is evident from the literature that combination of anode and cathode decides the overall cell voltage. The present investigation focuses on reduction of TCE (trichloro ethylene) using electro-reduced Co(I)(CN)54- and Ni(I)(CN)54-. At first, current density, temperature, and the anodic/cathode part has fixed by keeping Pt and Ag as anode and cathode, respectively, in 0.01 M Co(II)(CN)53- and Ni(II)(CN)53- in 10 M KOH constant. The reduction of Co(II)(CN)53- and Ni(II)(CN)53- confirmed via ORP electrode. The reduction efficiencies were calculated using titration with FeSO4 and KMnO4. Additionally, CV results supports the mediated reduction of TCE via Co(I)(CN)54-and Ni(I)(CN)54-. The GC analaysis showed product that fromed in the reduction process. Finally, there will be a discussion on the TCE reduction mechanism using electro-generated Co(I)(CN)54- and Ni(I)(CN)54-. |
