A novel pre-oxidation method for elemental mercury removal utilizing a complex vaporized absorbent

- An innovative liquid-phase complex absorbent (LCA) for Hg0 removal was prepared.
- A novel integrative process for Hg0 removal was proposed.
- The simultaneous removal efficiencies of SO2, NO and Hg0 were 100%, 79.5% and 80.4%, respectively.
- The reaction mechanism of simultaneous removal of SO2, NO and Hg0 was proposed.
