Abstract

We report on the results of kinetic and equilibrium adsorption measurements for two gases, CF₄ and Ar, on RPMI-Co and Cu-BTC metal-organic framework materials. The kinetic experiments were performed at similar relative temperatures (T/T_critical = 0.52 and 0.597) on both adsorbents. The results show that both gases behave differently on Cu-BTC from the way they do on RPM1-Co. In addition, the equilibrium isotherms indicate that there are some sites on Cu-BTC which are accessible to Ar but not to CF₄. Taken together, our results for the kinetic and equilibrium experiments suggest that these MOFs have high potential for use in gas separation applications.
