Title: STUDY ON CHELATE RESINS Syntheses of New Chelating Resins by the Reaction of Chloromethylthiirane with Polyethylene Polyamines
Abstract: A series of new amino-isopropylmercaptan type crosslinked chelating resins were prepared by the reaction of chloromethylthiirane with polyethylene polyamines H-(NHCH2CH2)-nNH2, n = 1, 2, 3, 4.These chelating resins exhibited excellent adsorption properties for the noble metal ions. The adsorption capacities for Ag+, Au3+, Pd2+ and Hg2+ were 5.3-6.6, 2.0-5.7, 2.6-4.6 and 3.8-5.7 mmol/g-resin respectively.
