Abstract An adsorption isotherm can be generally defined as an expression of the equilibrium, at constant temperature, relating the concentration of a species on an adsorbent surface to the concentration in the solution. It has been extensively used for decades to describe adsorption behavior and to estimate the adsorption capacity of activated carbon in various types of processes for removing organics from water. The unique advantages of the technique include ease of preparation and economy of money and time. The possible applications of isotherms may be summarized as (1) to select the best carbon among the alternatives; (2) to estimate the life of carbon in an adsorber; and (3) to test the remaining adsorption capacity of a working activated carbon adsorber. Isotherm capacities can be used directly or by incorporating them into a kinetic model to predict adsorber performance. The paper will focus on the measurement of capacity and its relationship to the measured life of a (GAC) adsorber.
