Carbon adsorption of

Adsorption — An important physico-chemical phenomenon used in treatment of hazardous wastes or in predicting the behavior of hazardous materials in natural systems is adsorption. Adsorption is the concentration or accumulation of substances at a surface or interface between media. Hazardous materials are often removed from water or air by adsorption onto activated carbon. Adsorption of organic hazardous materials onto soils or sediments is an important factor affecting their mobility in the environment. Adsorption may be predicted by use of a number of equations most commonly relating the concentration of a chemical at the surface or interface to the concentration in air or in solution, at equilibrium. These equations may be solved graphically using laboratory data to plot "isotherms." The most common application of adsorption is for the removal of organic compounds from water by activated carbon.

An empirical molecular descriptor proposed by Abe et. al. (1986) derived from a group contribution method based on molecular refractivity to predict the activated carbon adsorption of 157 compounds from aqueous solutions [Okouchi and Saegusa, 1989]. The adsorbability index for a molecule is calculated by the expression ...
