Sequestration of trace metals using water-soluble and fluorous phase-soluble polymers Academic Article

abstract

• Ion-exchange polymers with 'on'/'off' solubility can be prepared from N- isopropylacrylamide (PNIPAM) copolymers that incorporate hydroxamic acid ligands. Such complexing agents quantitatively remove trace amounts of Fe(III) from aqueous solutions (vial 1) by precipitating the metal-polymer complex on heating (suspension in vial 2). Physical separation of the insoluble polymer leaves a metal-free solution (vial 3). Similar fluorous phase-soluble hydroxamic acid derivatives of fluoroacrylate polymers remove Fe(III) ions from organic solutions by liquid/liquid phase separation.
