Research output: Patent

Abstract

Novel composite materials useful for removing heavy metal ions from solutions, such as aqueous waste streams, comprise an inorganic ceramic support, such as silica gel, having terminal hydroxy groups, to the oxygen of which a ligand is covalently bonded through a silane coupling agent, the ligand being a phosphorous or thiophosphorous based acid moiety.
