ADSORPTIVE SEPARATION OF HIGHLY VOLATILE CHLOROHYDROCARBONS FROM INERT-GASES WITH ADSORBENT POLYMERS AND ACTIVATED-CHARCOAL .1. ISOTHERMS AND KINETICS OF ADSORPTION

The behaviour of the adsorption (equilibrium and kinetics) of traditio nal and crosslinked polymeric adsorbents to 1.1.1-trichloroethane and trichloroethylene vapor was studied in comparison to activated carbons at 20 and 40 degrees C. The several Values for the adsorption isother ms were calculated from breakthrough curves using flow-through apparat us. The experimentally determined isotherms were well described with k nown models of isotherms. A graduation of the investigated adsorbents was accomplished regarding to the capacity of adsorption at the equili brium. The calculated kinetic parameters gave an information about the step that defines the rate of the adsorption process. These parameter s and the isotherms also are the basis for the prediction of breakthro ugh curves (part 2 of this publication series).
