Enormous efforts have been put to effectively treat or eliminate toluene, one of the most well-known volatile organic compounds (VOCs). Herein, we report its sorptive removal mechanism against metal-organic frameworks (MOFs: UiO-66, UiO-66(NH₂), ZIF-67, MOF-199, MOF-5, and MIL-101(Fe)) under ambient conditions. Their interactions were assessed by the Henry’s law constant (K_H) and the heat of adsorption (ΔH_ads). Although the equilibrated adsorption capacities of all MOFs were measured from 159 (MOF-199) to 252 mg g⁻¹ (UiO-66(NH₂)), those values were reduced considerably with increases in humidity and temperature. Among them, the sorption pattern of UiO-66(NH₂) was the most reproducible when tested over a three cycle (147 (1st) and 133 mg g⁻¹ (3rd cycle)). The behavior of single bondNH terminated MOFs (UiO-66(NH₂) and ZIF-67) was distinguished with those of single bondCOOH as …
