Chelating agents for heavy metal removal |
| abstract |
The present invention provides for Troika acids attached to a macroporous resin and Methods of preparing the same, including direct attachment of a Troika acid, and attachment of a Troika acid precursor followed by generation of the Troika acid in situ. Methods of functionalizing a resin to facilitate attachment are also described. Multiple Troika acids, comprising a pair of Troika acids joined together are described. Synthetic routes to both microporous and macroporous resins modified by introduction of a suitable Troika-type acid have been designed and validated. In a preferred embodiment, a macroporous Troika resin removes Cu 2+ and Ni 2+ from aqueous solution with high affinity, and is selective against Mg 2+ or Ca 2+ . The materials of the present invention have advantages for metal removal from power plant waste water. |
