To gain a more complete understanding of the impact of sulfur oxides on mercury capture by activated carbon, continuous mercury concentration measurements were made downstream of a packed sorbent bed. The results indicate that high S6+ content limits both the 6-h capacity of activated carbon and the initial mercury removal efficiency. Findings suggest that there are multiple available sites for mercury interaction with the sorbent surface and that capture and oxidation occur at different surface sites.
