Themercury removal performance ofmodified bamboo charcoal (BC) was investigatedwith a bench-scale fixedbed reactor. A simple impregnation method was used tomodify the BC with ZnCl

and FeCl

separately. BET and XPS were used to determine the pore structure and surface chemistry of the sorbents. The role of Fe

in the removal of elemental mercury bymodified sorbents was discussed. The experimental results suggest that themodified BCs have excellent adsorption potential for elemental mercury at a relatively higher temperature

140 ℃. The BET surface area and average pore size ofmodified sorbents do not shownoticeable priority compared to unmodified BC. XPS spectra indicate that Fe atoms mainly exist in the form of Fe

for the FeCl

-impregnated BC at different temperatures (20

140 and 180 ℃) suggests the enhancement of non-chloride functional groups (Fe

). Inhibition effect of SOx and NO for Hg
