Volatile Organic Compounds(VOCs) adsorption properties of Metal-Organic Framework(MOF) MIL-100(Fe), which a porous adsorbent with large surface area of about 1800 ㎡/g and pore volume of 0.92 ㎠/g, were investigated in this study. A number of techniques such as biofilteration, absorption, adsorption, membrane separation have been developed to control the VOCs emission and the removal of VOCs from contaminated air. Among those techniques, adsorption removal of VOCs using porous materials is effective technique for the air purification. We observed that the MIL-100(Fe) had a huge potential of used as a adsorbent for the adsorptive removal of VOCs including ammonia, trimethylamine, acetaldehyde, toluene and acetic acid. MIL-100(Fe) showed a higher adsorption capabilities for selected VOCs than Zeolite and Activated carbon. MOFs were superior to other porous materials commonly used including zeolite, activated carbon and their derivatives, because of their high porosity and easily tunable pore size and shape from microporous to mesoporous by changing the organic linkers. VOC molecules were captured in MIL-100(Fe) by the pore filling mechanism, which showed the size and shape selectivity of VOC molecules.

Metal Organic Framework (MOF) is porous material that is self assembled by coordinate covalent bond with metal cluster and organic ligand. Characterized by high surface area, catalytic activity, adsorption capacity, uniform porosity, ion exchange properties. In this work, we investigated antimicrobial activity and antimicrobial properties of MOF for 8 types harmful bacteria by various substrates. As a result, excellent antibacterial activity was confirmed against bacteria by MOF, It is expected to be applied as a new antimicrobial agent.
