Activated carbons are versatile adsorbents. Their adsorptive properties are due to their high surface area, a microporous structure, and a high degree of surface reactivity. They are, used, therefore, to purify, decolorize, deodorize, dechlorinate, separate, and concentrate in order to permit recovery and to filter, remove, or modify the harmful constituents from gases and liquid solutions. Consequently, activated carbon adsorption is of interest to many economic sectors and concern areas as diverse as food, pharmaceutical, chemical, petroleum, nuclear, automobile, and vacuum industries as well as for the treatment of drinking water, industrial and urban waste water, and industrial flue gases.
Interest in activated carbon adsorption of gases and vapors received a big boost during and after the first World War, while an increasing attention to the activated carbon adsorption from aqueous solutions was initiated by the pollution of the environment, which includes air and water, due to rapid industrialization and ever-increasing use of the amount and the variety of chemicals in almost every facet of human endeavor. Life has initiated increasing attention to the activated carbon adsorption from aqueous solutions. It was, therefore, thought worthwhile and opportune to prepare a text that describes the surface structure of activated carbons, the adsorption phenomenon, and the activated carbon adsorption of organics and inorganics from gaseous and aqueous phases.
