PCT No. PCT/US97/11054 Sec. 371 Date Dec. 14, 1998 Sec. 102(e) Date Dec. 14, 1998 PCT Filed Jun. 24, 1997 PCT Pub. No. WO97/49492 PCT Pub. Date Dec. 31, 1997A method and composition for the concentration and removal of desired metal ions from a source solution by contacting the solution with an N-cyclic aromatic hydrocarbon-containing ligand covalently bonded to a solid support through a hydrophilic spacer of the formula SS-A-X-(L)n where SS is a solid support, A is covalent linkage mechanism, X is a hydrophilic spacer grouping, L is an N-cyclic aromatic containing ligand group and n is an integer of 1 to 6. X or L combined will not contain more than two amine nitrogen atoms. There will preferably be at least four N-cyclic groups present of which pyridine, pyrimidine, pyraxine, imidazole, quinoline, isoquinoline, naphthyridine, pyridopyridine, phenanthroline are representative. The desired ions in the source solution are bound to the ligands and are subsequently separated by contacting the ligand containing compound with a smaller volume of a receiving solution that removes the bound ions for recovery in concentrated form in the smaller volume of the receiving solution.
