标题 :Synthesis of sequestration resins for water treatment in light water reactors
发明人：YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN
权利人:YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN; ELECTRIC POWER RES INST
摘要:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. 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 sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.
