Enhanced removal of NO by electro-scrubbing using a combination of consecutive MEO and MER process |
| 초록 |
A combined MER (mediated electrochemical reduction) and MEO (mediated electrochemical oxidation) approach was examined for the first time for the efficient removal of NO by electro-scrubbing. The generation of a mediator (Ni(I) from Ni(II)(CN)42- in 9 M KOH) by electrochemical reduction was identified by the changes in the ORP value and potentiometric titration. The MER of NO at the cathodic half-cell by electro-scrubbing revealed the formation of NH3 and N2. The reductive removal efficiency of NO was 100% up to a gas flow rate of 2 L min-1. At the anodic half-cell, the Co(III) mediator from Co(II)SO4 in 5 M H2SO4 was generated electrochemically with concomitant conversion of NO to NO3 in the solution phase with a removal efficiency of 28%. The combination of MEO and MER with electro-scrubbing demonstrates 100% removal efficiency of NO at a high gas flow rate of 4 L min-1. The combined removal approach is more suitable for high concentrated NO industrial sources. |
