Selective extraction of metal ions with polymeric extractants by ion exchange/redox
Patent
·
OSTI ID:866247
- Knoxville, TN
The specification discloses a method for the extraction of metal ions having a reduction potential of above about +0.3 from an aqueous solution. The method includes contacting the aqueous solution with a polymeric extractant having primary phosphinic acid groups, secondary phosphine oxide groups, or both phosphinic acid and phosphine oxide groups.
