description	PROBLEM TO BE SOLVED: To provide an organic synthesis of materials to remove low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions.SOLUTION: The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a metal ion sequestration resin. The synthesis further includes the steps of cooling the metal ion sequestration resin, washing and drying the metal ion sequestration resin, and removing any unconverted sulfonate sites from the metal ion sequestration resin.
