The present invention provides for Troika acids attached to a macroporous resinand Methods of preparing the same, including direct attachment of a Troika acid,and attachment of a Troika acid precursor followed by generation of the Troikaacid in situ. Methods of functionalizing a resin to facilitate attachmentare also described. Multiple Troika acids, comprising a pair of Troika acidsjoined together are described. Synthetic routes to both microporous and macroporousresins modified by introduction of a suitable Troika-type acid have been designedand validated. In a preferred embodiment, a macroporous Troika resin removesCu2+ and Ni2+ from aqueous solution with high affinity,and is selective against Mg2+ or Ca2+. The materials of thepresent invention have advantages for metal removal from power plant waste water. |
