摘要：

A series of polystyrene supported thiacrown ethers were prepared from cross-linked chloromethylated polystyrene (CMPS). CMPS was etherified with propenol to form poly (4-propenyloxy methyl styrene) (PA), followed by the bromoalkoxylation of PA with chloroethanol (CE) in the presence of N-bromosuccinimide, and the etherification with w, w'-dimercaptopolyglycols. Their complexation capacity, selectivity and mechanism towards metal ions, especially precious metal ions, were also investigated. The polymeric thiacrown ethers possessed a high complexation capacity and selectivity for Ag+ and Au3+ then Pd2+, Pt4+, Hg2+, Cu2+, Zn2+, Mg2+ and K+. XPS revealed that both oxygen and sulfur atoms in the ring contributed to the coordination with metal ions. (C) 1998 Elsevier Science Ltd. All rights reserved.
