ABSTRACT:
A composite material useful for removing heavy metal ions from solutions such as aqueous waste streams comprises a ceramic inorganic support such as silica gel which is covalently bonded, through a silane coupling agent, to a hydroxyquinoline ligand or such a support which has been reacted with a silylating agent and then on which is deposited a hydroxyquinoline ligand.
