Gaseous CCl4 removal using electrochemically generated homogeneous Ni(I)(CN)43- by electro-scrubbing |
| 초록 |
Gas pollutants must be removed to have healthy envirenmtal air for humans. Among amny ways to remove them, metal ions mediated electrochemical reduction (MER) is a futuristic technology. 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)42- especially at the Cu electrode in KOH medium. At a first step, Pt electrode as anode in 5 M H2SO4 in anodic part kept constant. Electrolytic reduction of Ni(II)(CN)42- identified by ORP variation and potentiametric titration. Suitability of cathodes form Ag, Ti, carbon, and Cu in 10 M KOH solution were tested. The reduction efficiencies changes calculated using titration with KMnO4. Cyclic voltammetry analysis at said electrodes corelated with the reduction of Ni(II)(CN)42-. A model gas pollutant CCl4 removal carried out by electro-scrubbing with online FTIR gas analyzer. |
