Title:
重金属除去用キレート剤
Document Type and Number:
Japanese Patent JP2008514419
Kind Code:
A
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 Cu2+ and Ni2+ from aqueous solution with high affinity, and is selective against Mg2+ or Ca2+. The materials of the present invention have advantages for metal removal from power plant waste water.
