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