Description

Water pollution is becoming increasingly serious with global economic development and the sophistication of industrial structures. In aquatic environments, perfluorinated compounds pose particular risks because of their extreme stability, which endows them with serious environmental persistence and bioaccumulation properties. Moreover, their detoxification via decomposition is difficult. Here, we studied the adsorptive removal of perfluorooctane sulfonate (PFOS) as a class of perfluorinated compounds using metal–organic frameworks (MOFs), which are porous coordination polymers, as new adsorbents. The potential of the porous imidazolate framework ZIF-67 and the porous terephthalate framework UiO-66 as PFOS adsorbents was verified on the basis of the effect of downsizing the crystal and modification with functional groups, respectively.
