Patent number: 7332089Abstract: 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.Type: GrantFiled: September 30, 2003Date of Patent: February 19, 2008Assignee: INEOS Silicas Ltd.Inventors: Risto Olavi Harjula, Johanna Teresia Moller, Suheel Amin, Alan Dyer, Martyn Pillinger, Jonathan Andrew Newton, Esko Heikki Tusa, Maurice Webb

Patent number: 6926912Abstract: A non-aluminum containing mixed metal compound for pharmaceutical use, which may, for example, be a mixed metal hydroxy carbonate containing magnesium and iron, and may have a hydrotalcite structure, preferably a non-aged hydrotalcite structure. Other metals, including, for example, calcium, lanthanum and cerium, may also be used. Metal sulphate compounds, especially calcium sulphate, lanthanum sulphate and/or cerium sulphate, compounds are also useful. The mixed metal compounds have a phosphate binding capacity of at least 30%, by weight, based on the test methods 1, 2 or 3, described in the specification, over a pH range from 3 to 7, such as from 2 to 8. The compound is especially useful in the treatment of hyperphosphataemia.Type: GrantFiled: September 18, 1998Date of Patent: August 9, 2005Assignee: Ineos Silicas LimitedInventors: Norman B Roberts, Maurice Webb, Benjamin J Rankin

Patent number: 5360547Abstract: A method of treating a liquid medium to remove from it matter present therein comprises adding to the liquid medium at least one of an at least partially undried sorbing agent (a), a freshly prepared sorbing agent (b) and an in-situ sorbing agent (c). Sorbing agent (a) comprises a hydrotalcite-like material resulting from the preparation thereof in a liquid reaction medium, which preparation allows retention, in the hydrotalcite-like material, of at least 10% of free liquid, based on the weight of the hydrotalcite-like material, including the free liquid, and (a).sub.1 which sorbing agent is present in an amount, on a dry weight basis, of the sorbing agent, by volume of the liquid medium to be treated, of .ltoreq.0.035% w/v, or (a).sub.2 the preparation of the hydrotalcite-like material is such as to provide a grain size of the hydrotalcite-like material of .ltoreq.130 .ANG., as measured in the <001> direction by x-ray diffraction on a subsequently dried material.Type: GrantFiled: March 29, 1993Date of Patent: November 1, 1994Assignee: Unilever Patent Holdings B.V.Inventors: Keith R.

Patent number: 5246467Abstract: It is necessary to remove unbound reactive dyes from the surfaces of textile substrates treated with dyes of this class; this is to ensure the dyed substrate is fast. In the invention dye is removed from a wash medium by contracting the medium with an absorbent, preferably a hydrotalcite-like material, which removes suspended dye. This removal allows re-use of the wash medium or its disposal.Type: GrantFiled: March 18, 1992Date of Patent: September 21, 1993Assignee: Unilever Patent Holdings B.V.Inventors: Keith R. F. Cockett, Martin Concannon, Maurice Webb
