    摘要: Metal-organic framework (MOF) materials are provided and are selectively adsorbent to xenon (Xe) over another noble gas such as krypton (Kr) and/or argon (Ar) as a result of having framework voids (pores) sized to this end. MOF materials having pores that are capable of accommodating a Xe atom but have a small enough pore size to receive no more than one Xe atom are desired to preferentially adsorb Xe over Kr in a multi-component (Xe—Kr mixture) adsorption method. The MOF material has 20% or more, preferably 40% or more, of the total pore volume in a pore size range of 0.45-0.75 nm which can selectively adsorb Xe over Kr in a multi-component Xe—Kr mixture over a pressure range of 0.01 to 1.0 MPa.

    摘要: The present invention provides for a permeable reactive barrier and an effective method of removing contaminants from water using adsorbent powders, such as zero valent iron particles, adhered throughout a reticulated foam structure. This structure provides improved mass transfer, higher reaction rates and reduced residence times. The barrier includes a reticulated foam substrate with high permeability, an adherent coating and a reactive adsorbent arranged in a reticulated foam structure. The substrate can be selected from various materials including polyurethane and polyester. The adherent may be selected from a wide range of materials including polyurethanes, acrylics, silicones, siliconized acrylics, latex emulsions, and other inherently tacky materials that cure to a water resistant coating. The reactive adsorbent can be selected from various adsorbents including a powdered zero-valent iron (ZVI).
