摘要: 含硫、氮配位原子的螯合树脂对贵金属具有良好的吸附性能.本工作合成的以聚硫醚为主链,侧链为多乙烯多胺的树脂尚未见文献报道.这类树脂硫、氮含量较高,主链和侧链均能对贵金属离子起络合作用,故对Au3+、Ag+、Pd2+、Pt+等具有较强的吸附能力.树脂的合成路线和预期的主要结构如下.

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.
