title: Efficient extraction of sulfate from water using a Zr-metal-organic framework.
abstract: A Zr-based MOF, NU-1000, comprised of Zr6 nodes and tetratopic pyrene-containing linkers is studied for adsorption and extraction of SO4(2-) from water. The adsorption capacity and uptake time of SO4(2-) in NU-1000 is determined at varying concentrations to give an overall maximum adsorption capacity of 56 mg SO4(2-) per g of MOF. Selective adsorption of SO4(2-) by NU-1000 in the presence of other anions as well as regeneration of the sorbent is also explored.
