Metal-Organic Framework Templated Inorganic Sorbents for Rapid and Efficient Extraction of Heavy Metals

An innovative wet‐treatment with Na2S transforms two indium metal‐organic frameworks (MOFs) into a series of porous inorganic sorbents. These MOF‐templated materials display remarkable affinity for heavy metals with saturation occurring in less than 1 h. The saturation capacity for Hg(II) exceeds 2...

Description
Summary:An innovative wet‐treatment with Na2S transforms two indium metal‐organic frameworks (MOFs) into a series of porous inorganic sorbents. These MOF‐templated materials display remarkable affinity for heavy metals with saturation occurring in less than 1 h. The saturation capacity for Hg(II) exceeds 2 g g‐1, more than doubling the best thiol‐functionalized sorbents in the literature.
