摘要

Anchoring the hydroxyaspartic acid onto poly(glycidyl methacrylate-co-ethylene dimethacrylate) (poly(GMA-co-EDMA)) beads or eoxysuccinic acid onto ammonium-modified poly(GMA-co-EDMA) beads resulted in a novel chelating resin, which contained up to 0.37 mmol of the ligand per gram of resin. Batch extraction experiments showed a very hgih selectivity for Cu~(2+) over Zn~(2+) and Cd~(2+) ions in buffered solutions under competitive conditions.
