Selective electrochemical formation of Cu1+ in Cu(Ni(CN)4)3- complex towards gaseous CF4 degradation at electro-scrubbing |
| 초록 |
. Growing semiconducting industries leaves similar amount of CF4 to the environment that are dangerous to the healthy environment and humans. Among few ways to remove CF4, electrochemical way of its removal become simple and 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 removal of gaseous CF4 using electrogenerated Cu(I)[Ni(II)(CN)4]2- in KOH medium. At a first step, electrochemical reduction of Cu(II)[Ni(CN)4]2- was optimized at different electrodes like TiO2, Ag, carbon. The reduction efficiencies changes calculated using titration with KMnO4. Cyclic voltammetry analysis at said electrodes correlated with the reduction of Ni(II)(CN)42-. Finally, CF4 removal was carried out under optimized conditions using electro-scrubbing with online FTIR gas analyzer and removal efficiency found 99%. |
