Three metal organic frameworks, MIL-101, MIL-53 and CPM-5, are used for VOCs adsorption. Adsorption isotherms and TGA indicates the physisorption of toluene and isobutanol on these MOFs. In dry air, MIL-101 shows the highest adsorption capacity for one ppm of toluene and isobutanol. At 30% relative humidity, MIL-53 demonstrates the highest adsorption capacity of toluene. CPM-5 shows the least adsorption capacity for toluene and isobutanol in both dry and humid air.
