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.

Rapid, Selective Heavy Metal Removal from Water by a Metal–Organic Framework/Polydopamine Composite

Journal Article Sun, Daniel T. ; Peng, Li ; Reeder, Washington S. ; ... - ACS Central Science

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, water stable metal–organic framework/polymer composite, Fe-BTC/PDA, that exhibits rapid, selective removal of large quantities of heavy metals, such as Pb2+ and Hg2+, from real world water samples. In this work, Fe-BTC is treated with dopamine, which undergoes a spontaneous polymerization to polydopamine (PDA) within its pores via the Fe3+ open metal sites. The PDA, pinned on the internal MOF surface, gains extrinsic porosity, resulting in amore »« less

Efficient extraction of inorganic selenium from water by a Zr metal–organic framework: investigation of volumetric uptake capacity and binding motifs

Journal Article Drout, Riki J. ; Howarth, Ashlee J. ; Otake, Ken-ichi ; ... - CrystEngComm

Strict monitoring and control of selenium concentrations in freshwater supplies is critical to safeguarding human health and aquatic life. A handful of previously investigated sorbents exhibit noteworthy gravimetric (mg g ^-1) Se uptake capacities; however, often display insufficient volumetric (mg cm ^-3) capacities, thereby requiring large volumes of material for commercial implementation. In this paper, in pursuit of mitigating this material inefficiency, we investigated the selenite (SeO ₃ ^2-) and selenate (SeO ₄ ^2-) affinity of MOF-808, a Zr-based metal–organic framework with a high density of potential Se oxyanion binding sites. MOF-808 recorded exceptional volumetric and gravimetric Se oxyanion capacitiesmore »« less

Efficient Capture of Perrhenate and Pertechnetate by a Mesoporous Zr Metal–Organic Framework and Examination of Anion Binding Motifs

Journal Article Drout, Riki J. ; Otake, Kenichi ; Howarth, Ashlee J. ; ... - Chemistry of Materials

At the Hanford Site in southeastern Washington state, the U.S. Department of Energy intends to treat 56 million gallons of legacy nuclear waste by encasing it in borosilicate glass via vitrification. This process ineffectively captures radioactive pertechnetate (TcO ₄–) because of the ion’s volatility, thereby requiring a different remediation method for this long-lived (t _1/2 = 2.1 × 10 ⁵ years), environmentally mobile species. Currently available sorbents lack the desired combination of high uptake capacity, fast kinetics, and selectivity. Here, we evaluate the ability of the chemically and thermally robust Zr ₆-based metal–organic framework (MOF), NU-1000, to capture perrhenate (ReOmore »« less
