ABSTRACT:
Novel ceramic compositions are used for removing metal ions by chelation from solutions such as aqueous waste streams. The compositions are formed by covalently bonding to terminal hydroxy groups of a ceramic inorganic carrier or support a substituted silane linking group attached to a chelating agent or ligand which is pyrogallol or a derivative thereof.
