Study on Mercury Adsorption Performance of Modified Fly Ash

Abstract:

The fly ash was modified by Cl, Fe, Cu salts to investigate the mercury adsorption performance and analyze the impacts on it. Experiment results indicate that significant improvement of removal efficiencies with FeCl₃、CuCl₂ and CuBr₂ impregnation onto fly ash. The modification adjusted the pore structure of fly ash and formed more pores to absorb Hg, also it was found that new active sites were generated after the treatment, which can oxidize Hg⁰ and improve chemical adsorption.
