A method for estimating thermal desorption curves and desorption efficiencies of organic solvents from activated carbon was developed for the determination of adsorbed solvent by thermal desorption method, and the estimated values were compared with the experimental values. The Freundlich or the Langmuir isotherm was assumed in obtaining the solution. Thermal desorption experiments were conducted by the following two methods: a) Desorption of solvents which were adsorbed in the activated carbon at the desorption temperature under the nitrogen gas flow containing vapor until the system reached its equilibrium state. b) Desorption of solvents which were adsorbed in the activated carbon previously at room temperature. The model was based on a) method, but the estimated desorption curves and desorption efficiencies agree well with the experimental ones not only for a) method but also for b) method.
