Abstract
Nickel was loaded on the activated carbon fiber(ACF) surface, by adsorption and sintering. In order to change the chemical functional groups on the carbon fiber surface, and increase catalytic oxidation capacity and removal efficiency of activated carbon fiber to element mercury. The samples of ACF were characterized before and after loading, using XPS and XRD. The results show that the nickel content in the ACF surface was 3.36at.%. The presence of nickel form was NiO and Ni. The adsorption ability of elemental mercury before and after modification was also studied. The breakthrough time was greatly extended after loading. At 95 , the ACF loaded nickel showed the best adsorption performance.
