title = "Adsorptive removal of Sb(V) from water using a mesoporous Zr-based metal–organic framework",
abstract = "The adsorption and removal of Sb(OH)6 − from water using the water stable Zr6-based MOF, NU-1000, is explored. The adsorption capacity and uptake time of Sb(OH)6 − in NU-1000 is measured at varying concentrations to determine an overall maximum adsorption capacity of 260 mg of Sb(OH)6 − per g of MOF, corresponding to 2.5 Sb(OH)6 − per node of NU-1000 and exhibiting the highest adsorption capacity of any material reported to date for Sb(V) removal. Differential pair distribution function (dPDF) analysis of total X-ray scattering data reveals that Sb(OH)6 − interacts in an η2μ2 fashion with the Zr6-node of NU-1000, and that as the amount of Sb(OH)6 − adsorbed increases, the interaction between the analyte and the node becomes stronger. Post-adsorption characterization shows that NU-1000 remains stable throughout the adsorption process.",
