Abstract
The present invention relates to an organo-ceramic composite material useful for the extraction of metal ions from solution. The organo-ceramic composite material is formed according to a sol gel synthesis scheme by reacting a functional precursor silane and its homopolymers with either (i) a mixture of a cross-linking silane and its homopolymers or (ii) the cross-linking silane, under conditions effective to yield the composite material of the present invention. Further aspects of the present invention relate to methods of removing a metal ion from a water stream and recovering a metal ion from a water stream, both of which include contacting a water stream containing a metal ion with an organo-ceramic composite material of the present invention under conditions effective to remove the metal ion from the water stream.
