Abstract

Adsorption equilibria of toluene on various polymeric adsorbents were obtained by a static volumetric technique. The polymeric adsorbents used were Ambersorb 600 (Rohm and Haas Co.), Sp 850 (Mitsubishi Chemical Co.), and Dowex Optipore V493 (Dow Chemical Co.). The equilibrium measurements were done at 273.15, 298.15, 323.15, and 348.15 K and pressures up to 2.95 kPa for toluene. The experimental data of Ambersorb 600 were correlated by the Unilan equation and the Dubinin-Astakhov (D-A) equation was used to correlate experimental data of Sp 850 and Dowex Optipore V493. The isosteric heat of adsorption was calculated. It was found that the values of isosteric heat of adsorption varied with surface loading.
