Adsorption of 1,1,1‐trichloroethane Vapor by granular activated carbons

Abstract

A laboratory investigation on the adsorption of hazardous 1,1,1‐Trichloroethane (TCEA) vapor on the granular activated carbons BPL and PCB, which were made from bituminous coal and coconut shell, respectively, was conducted at 283, 293, 303, and 313 K. The experimental results indicate that the adsorption capacity of carbon PCB is higher than that of carbon BPL. The Langmuir, Freundlich, and Dubinin‐Radushkevich adsorption equations were found to well represent the measured adsorption data. The values of the parameters of the adsorption equations were determined for the two adsorbents. The physical properties (e.g. micropore volume) of the adsorbents are consistent with the parameters obtained from the adsorption results.
