Syntheses of new types of chelating resins and their adsorption properties for noble metals

摘要

Three new types of chelating resins containing nitrogen and sulfur or oxygen atoms as coordination atom were synthesized by the reaction of a polymer bearing amino (-NH2) or imino (=NH) groups as reaction sites with a substitutive derivative of epithiopropane or epoxypropane. These resins exhibited excellent adsorption properties for noble metals.
