In order to better understand the adsorption of volatile halogenated anesthetics on metal organic frameworks (MOFs), sevoflurane vapor adsorption experiments were performed on commercial MOF-177 at different temperatures. Due to the surface homogeneity of such an adsorbent, arising from its almost unimodal pore size distribution and the absence of specific, coordinatively unsaturated adsorption active sites, sevoflurane adsorption isotherms exhibited a peculiar deviation from the Langmuirian behavior. Consequently, they show a "kink" at a specific pressure that increases with increasing equilibrium temperature. Successful modeling of such data by means of the Talu-Meunier equation confirmed clustering of adsorbate molecules inside adsorbent micropores, similarly to water vapor adsorption on activated carbon, which may play an important role when designing a system using MOFs as the potential adsorbents for capturing anesthetics.
为了更好地理解挥发性卤代麻醉剂在金属有机骨架（MOFs）上的吸附，在不同温度下对商业 MOF-177 进行了七氟醚蒸气吸附实验。由于这种吸附剂表面均匀，具有几乎单模态的孔径分布，并且不存在特定的、配位不饱和的吸附活性位，因此七氟醚吸附等温线表现出与朗缪尔行为的奇特偏离。因此，它们在特定压力下显示出“拐点”，随着平衡温度的升高而增加。通过 Talu-Meunier 方程成功地对这些数据进行建模，证实了吸附质分子在吸附剂微孔内的聚集，类似于水蒸气在活性炭上的吸附，这在设计使用 MOFs 作为潜在吸附剂捕获麻醉剂的系统时可能具有重要作用。
