英文摘要: Abstract(#br)This article investigates the properties of surface oxygen-containing functional groups (SOFG) on activated carbons, and their effects on removal of gaseous mercury chloride (HgCl 2 ). For this purpose, the surface of a coal-based commercial activated carbon BPL was modified by heating in an inert atmosphere and then impregnated with benzoic acid solution. Afterwards, all carbonaceous samples were tested for their HgCl 2 adsorption capacities. Nitrogen (N 2 ) adsorption, Fourier Transform Infrared Spectroscopy (FT-IR) and Boehm titration were applied to study the surface characteristics of carbon samples. It was found that after benzoic acid impregnation, the amounts of SOFG improved with the increasing of benzoic acid concentration, especially carboxylic and carbonyl groups....
