摘要：

A procedure of extracting the adsorption parameters (alpha and gamma) of an adsorbent-adsorbate pair, from desorption studies is described. The method is validated through experiments on a powder specimen of activated charcoal with nitrogen as adsorbate and comparing the results with isotherm data from volumetric method. Adsorption isotherms for two more granular samples of activated carbon are generated with nitrogen as adsorbate. The value of gamma is found be about 0.1 for all samples, while of values ranged from about 0.4 for granular samples to 0.6 for powder specimen. (C) 2000 Elsevier Science Ltd. All rights reserved.
