Abstract:
A composition for selectively binding metal ions comprising a polyhydroxypyridinone-containing ligand covalently bonded to a particulate solid support through a hydrophilic spacer having the formula:SS-A-X-L(HOPO).sub.nwhere SS is a particulate solid support, A is a covalent linkage mechanism, X is a hydrophilic spacer grouping, L is a ligand carrier, HOPO is a hydroxypyridinone appropriately spaced on the ligand carrier to provide a minimum of six functional coordination metal binding sites, and n is an integer of 3 to 6 with the proviso that when SS is a particulate organic polymer, A-X may be combined as a single covalent linkage.
