Novel method for removal of NOx and SO2 by sustainable electrochemical process using Ag(I)/Ag(II) redox mediator
E-mail:
The objective of this work was to develop a process for removal of industrial waste gases like NO, NO2 and SO2 by electrochemically generated Ag(I)/Ag(II) redox mediator system in aqueous nitric acid medium. 100% removal efficiencies were achieved in these studies for removal of NOx and SO2 with Ag(II) ions in room temperature and atmospheric pressure. This Ag(I)/Ag(II) redox mediator system can be regenerated continuously during the scrubbing process.
