Title: Adsorptive removal of Sb(V) from water using a mesoporous Zr-based metal–organic framework

Abstract

Here, the adsorption and removal of Sb(OH) 6 - from water using the water stable Zr 6-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 η 2μ 2 fashion with the Zr 6-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.
