Title:
ION EXCHANGE MATERIALS
Document Type and Number:
WIPO Patent Application WO1999058243
Kind Code:
A3
Abstract:
A method of selectively removing a target metal cation from a liquid medium containing at least one other metal cation involves the use of an ion exchange material selected from four groups: 1) crystalline materials synthesised from octahedral/tetrahedral co-ordination polyhedra; 2) layered oxide materials, including those with inorganic pillars incorporated between the layers; 3) high silica materials, including those with large mesoporosity; and 4) microporous materials with interstitial cations other than Si or Al in tetrahedral co-ordination. At least one of the pore size, the layer charge density, the interlayer cations and the doping metal cations are controlled to render the ion exchange material selective towards the target metal cation.
