||The paper gives results of an investigation of the sorption and desorption of gaseous elemental mercury by activated carbon sorbents. Two sorbents were chosen for the study, one (PC-100) thermally activated and the other (HGR) chemically impregnated with sulfur. The sorbents had similar particle size (approximately 20 micrometers) and surface area (approximately 1000 sq m/g). Different reaction conditions of temmperature--23 C (or ambient) and 140 C--and mercury concentration (30 and 60 ppb in nitrogen) were used. The type of activated carbon, the temperature, and the mercury concentration showed strong effects on overall sorption behavior. At 140 C, chemisorption was found to be the only mechanism for elemental mercury capture for both sorbents.
