Cheiatinc Resins With NnRtxjEi+CoNTAiNiNc Pendant Groups 

Many workers have proposed chelating ligands based on polyfvinylimidazole) or polyfvinylimidazole) decaiboxylate groups. It has been suggested that die loading rates for base metals, Cu(D), Ni(H), and Co(H) are enhanced with this type of structural modification. 

Hydroxyamine polymers have also been explored extmsively. Vernon and Etxles have prepared several hydroxyoxime-type polymers and recommended their use for copper separation from iron at low pH value. Amidoxime-type fonctional groups are found to chelate uranium at low concentrations in seawater and to offer a potential solution to the problem of separating heavy metals fnun acidic solutions.
