  • Method and sorbent for selective removal of contaminants from fluids
    Patent number: 7407587
    Abstract: Anion exchange materials loaded with oxygen-containing metal compounds within the exchange matrix as a sorbent, and a method for preparation. The materials remove arsenic and other ligands or contaminants from water and other fluid streams.
    Type: Grant

  • Method of extracting metal ions from an aqueous solution utilizing an antimony silicate sorbent
    Patent number: 7332089
    Abstract: The invention provides a use of a material comprising antimony silicate as a sorbent in the removal of metal ions, e.g. radioactive metal ions, from an acidic liquid medium. The metal ions may be selectively removed from amongst other ions such as Na, K, Mg, and Ca ions. Strontium is particularly effectively removable in this way. There is also provided a method of preparing an antimony silicate material for use in removing metal ions. The invention further provides a material comprising antimony silicate doped with one or more elements selected from the group consisting of tungsten, niobium and tantalum. The doped material has been found to be particularly effective as a sorbent in the removal of metal ions from a liquid medium.
