Fe3O4@MIL-101 – A Selective and Regenerable Adsorbent for the Removal of As Species from Water
Issue Date
4-2016
Abstract
The chromium-based metal–organic framework MIL-101(Cr) served as a host for the in situ synthesis of Fe3O4nanoparticles. This hybrid nanomaterial was tested as an adsorbent for arsenite and arsenate species in groundwater and surface water and showed excellent affinity towards AsIIIand AsVspecies. The adsorption capacities of 121.5 and 80.0 mg g–1for arsenite and arsenate species, respectively, are unprecedented. The presence of Ca2+, Mg2+, and phosphate ions and natural organic matter does not affect the removal efficiency or the selectivity. The structural integrity of the hybrid nanomaterial was maintained during the adsorption process and even after desorption through phosphate elution. Additionally, no significant leaching of Cr or Fe species was observed.
