Nitrogen oxide research in surface science is closely tied to the fact that nitrogen oxides are important molecules in atmospheric chemistry and major components of air pollution. Studies of the surface reaction of nitrogen oxides with impregnated activated carbon are important for both monitoring the level of pollutants in that atmosphere and for reducing the emission of these compounds into the atmosphere. Thus, information gained in fundamental surface chemistry research regarding the bonding interactions with and energetics of molecules on activated carbon with impregnated chemical is necessary in order to improve the technology used in air quality control. Commercial adsorbents for treating harmful gas usually consist of small metal particles dispersed on a stable, high surface area support material such as activated carbon. The selective adsorption site of the adsorbent is generally at the surface of the metal particles. Therefore, the development of or improvement upon efficient impregnated activated carbons requires a good understanding of how adsorbates react on metal surfaces. The purpose of this study was, through a breakthrough experiment by use of fixed bed adsorption column, to examine surface reaction phenomena according to surface characterization that was adsorbed between NOx and potassium hydroxide impregnated activated carbon (K-IAC). |
