Patent number: 6248842Abstract: Selective, crosslinked chelating polymers are produced by substituting an acyclic chelating agent with a polymerizable functional group. The resulting substituted acyclic chelating agent is then complexed with the target metal ion. A crosslinkable monomer is then added and the complexed material is crosslinked. The complexed metal is then removed, providing a crosslinked polymeric chelating agent that has been templated for the target metal ion.Type: GrantFiled: February 25, 1999Date of Patent: June 19, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventors: Alok Singh, Eddie L. Chang
