摘要

Abstract

Elemental mercury(Hg

)re-emissions from slurries and solutions were evaluated in a lab-scale simulated scrubber.Oxidized mercury(Hg

)standard solution was injected into the simulated scrubber at a desired rate to simulate absorbing and dissolving of Hg

in the flue gas across wet flue gas desulfurization(WFGD)systems. PS analytical mercury analyzer was used to continuously determine Hg0re-emission concentrations in the carrier gas from the scrubber.Sulfite ion in the slurry of CaSO

was validated to reduce Hg

to Hg

while no Hg

re-emission occurred from slurries of CaSO

and CaO.Transitional metal ions with low chemical valence such as Fe

AsO

-1.Reduction reaction of Hg

to Hg

was observed from these solutions.Reduction capabilities for the different transitional metal ions in the solutions were:Pb

AsO
