Abstract

Abstract: By reacting polychloromethylthiirane with polyethylene Polyamincs four novel crosslinked chelating resins (PAl-4) containing thioether backbone with polyethylene polyimines in side chain were synthesized. The resins possessed excellent adsorbability for noble metal ions. The maximum adsorption capacities of the resins for Au(Ⅲ), Pd(Ⅱ), Pt(Ⅳ), Ag(Ⅰ) Zn(Ⅱ), and Pb(Ⅱ) were 1.11, 0.64, 0.68g metal/g resin and 5.07, 0.38, 0,36 mmol/g resin respectively. From the solution containing Ag(Ⅰ). Cu(Ⅱ), Zn(Ⅱ)and Cd(Ⅱ) the resins adsorpted Ag(Ⅰ) uniquely.

Key words: Chelating resin, Polythioether, Polyimine, Adsorbability, Nobel metal ion
