Title: STUDY ON CHELATE RESINS——VIII. Syntheses and Adsorption Properties of Chelate Resins Containing A Polythioether Backbone and Dioxymonosulfur Polyethylene Polyimines in Side Chain
Abstract: Four new chelate resins (PB1-4) containing a polythioether backbone and dioxymonosulfur polyethylene polyimines in side chain were synthesized by the reaction of poly (2'-chloroethyl-2, 3-epithiopropyl ether) with polyethylene polyamines. The adsorption capacities of resin PB for metal ions such as Au(Ⅲ), Pd(Ⅱ), Pt(IV), Ag+,Hg2+, Zn2+ and Pb2+ were determined and compared with the corresponding resin PC containing polyether backbone. The experimental results showed that the resin PB, especially PB3 and PB4, possessed good adsorption ability for noble metal ions. The maximum adsorption capacities for Au(Ⅲ), Pd(Ⅱ) and Pt(IV) were 1.47, 0.54 and 0.78 g metal/g resin, respectively. But the capacities of the resin PC were much lower than that of the resin PB. It is obvious that polythioether mainchain in the resin PB plays an important role in adsorption of noble metal ions.
