Abstract
Disclosed is a method for removing an ionic species contained in an aqueous phase. The method includes contacting an aqueous phase containing the ionic species with a sol-gel composite material, where the sol-gel composite material is a sol-gel composition having a porous matrix and containing a reactive metal incorporated into at least a portion of the porous matrix, under conditions sufficient to remove the ionic species contained in the aqueous phase.
