  • Adsorbents
    Patent number: 8747675
    Abstract: An adsorbent suitable for heavy metal absorption is described, comprising a thiol-functionalised support containing a stabilising amount of an alkaline metal reacted with said thiol functionality. The adsorbent may be used to remove heavy metals e.g. mercury and/or arsenic, from wastewater streams such as produced water or flue gas scrubber waters.

  • SORBENT
    Publication number: 20130053234
    Abstract: A method for preparing a sorbent composition includes the steps of: (i) applying, from a solution or a slurry, a layer of a copper compound on the surface of a support material, and (ii) drying the coated support material, wherein the thickness of the copper compound layer on the dried support is in the range 1-200 ?m. The precursor may be converted to a sorbent suitable for removing heavy metals from liquids or gases by applying one or more sulphur compounds to sulphide the copper compound and form CuS.
