| Abstract: | "Indoor exposure to volatile organic compounds (VOCs) is detrimental to the health of the occupants, and their removal is crucial in maintaining good air quality. Novel adsorbents prepared by modifying Metal-Organic Frameworks (MOFs), MIL101 (Cr), UiO-66, and UiO-66-NH(2) with [BMIM][CH(3)COO] ionic liquid, were characterized and tested for toluene adsorption. [BMIM][CH(3)COO]/MIL101 performed best with a fast sorption rate, large sorption capacity, and good regenerability. It displays synergistic interactions between the IL and MOF. Adding one weight percent [BMIM][CH(3)COO] to UiO-66 and UiO-66-NH(2) has a synergistic effect with respective 14% and 5% enhancements sorption over calculated values. The strong interactions between IL and UiO-66 and UiO-66-NH(2), as observed in their thermogravimetric data, results in poor toluene sorption for 10 wt% [BMIM][CH(3)COO] loadings. This work provides a basis for IL modification of MOFs for enhanced sorption of VOCs for air treatment" |
