Abstract

UiO-66 and analogues were successfully tailored to chemoselectively capture As^V oxyanions at the hydroxylated node and neutral As^III species with the thiolated organic linkers. More efficient and faster uptake can be achieved with increasing defect densities, increasing pore aperture sizes, and decreasing particle sizes.
