Synthesis and evaluation of water-soluble chelating polymers for the selective removal of actinide metal ions
- Los Alamos National Lab., NM (United States); and others
A major goal of our research program is to develop polymer supported ion specific ligand systems for the removal of actinides and other hazardous metals from wastewaters. The advantage of water-soluble polymers in metal ion separation processes is that the homogeneity of the system allows for more rapid exchange kinetics than ion exchange or chelating resins. A number of water-soluble chelating polymers have been synthesized by the functionalization or commercially available polyamine precursors with various ligand moieties such as hydroxamates. The ability of these polymers to complex with metal ion to give soluble complexes which can be separated and concentrated by ultrafiltration under different pH conditions have been examined.
