摘要： 利用Gabriel反应以聚环硫氯丙烷为起始物合成4种新型的以聚硫醚为主链的伯胺型树脂,研究了树脂的合成条件及吸附性能.这些树脂对贵金属离子有很高的吸附容量,其中每克树脂对Au(Ⅲ)的吸附容量达到5～7mmol,对Ag+的为7～9mmol;而对贱金属离子吸附甚少.可望用于贵金属离子Au(Ⅲ)和Ag+的分离与富集.

Abstract: Four new chelating resins containing polythioether backbone and primary amino group inside chain were synthesized from poly(chloromethyl thiirane) by Gabriel reaction in this paper. The preparation conditions were optimized, and the sorption properties of these resins were thoroughly studied. It was found that these resins possessed high capacities for sorpting noble metal ions, especially for Au(Ⅲ) (5～7 mmol for per gram resin) and Ag+ (7～9 mmol for per gram resin), but weak sorbabilities for non noble metal ions, such as Fe 3+, Cu 2+ and Zn 2+ . They are expected to be used in separations and enrichments of noble metal ions.

Key words: Chelating resin, Poly(chloromethyl thiirane), Noble metal sorption, Gabriel reaction
