摘要：
Carbon dioxide(CO 2) adsorption on a standard metal-organic framework MIL-101 and a pentaethylenehexamine modified MIL-101(PEHAMIL-101) are investigated and compared in this study.The adsorbent samples were characterized by XRD,FT-IR and nitrogen adsorptiondesorption isotherms analysis.CO 2 adsorption capacity was measured by a volumetric method.MIL-101 and PEHA-MIL-101 exhibited CO 2 adsorption capacities of 0.85 and 1.3 mmol CO 2 /g adsorbent at 10 bar and 298 K,respectively.It is observed that CO 2 adsorption capacity was fairly improved about 50% after amine modification.
