Electrochemical enhancement of high-efficiency wet removal of mercury from flue gas.

Electrochemical wet absorption composite system has an excellent potential to remove Hg from flue gas. In this study, ruthenium iridium titanium platinum quaternary composite electrode is used as an anode and titanium electrode is used as the cathode, and KI/I absorption solution is introduced into the electrocatalysis system as an electrolyte to form KI/I electrochemical catalytic oxidation system. The removal rate of Hg in flue gas can be increased to 92.
