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.
