摘要

介绍了在商业大孔聚苯乙烯聚合物基体上接枝硫脲官能团合成几种配位聚合物的方法。本文还报道了从酸性氯化物溶液中吸附和洗脱贵金属离子(或与贱金属离子Cu2+和Fe3+一起)的研究。结果表明,该树脂对酸性溶液中的金具有较好的吸附能力和选择性。树脂的萃取动力学比相应的单分子“自由”萃取剂类似物慢。然而,有些树脂的萃取率是可以接受的。

Thiourea-based coordinating polymers: synthesis and binding to noble metals

The synthesis of several coordinating polymers by grafting thiourea functional groups onto commercial macroporous polystyrene polymer matrices are described. In this paper, we also report the study on the absorption and elution of precious metal ions (or together with base metal ions, Cu2+ and Fe3+) from acidic chloride solutions. The results showed that these resins have appreciable capacity and good selectivity for the absorption of gold from acidic solutions. The extraction kinetics of the resins is slower than the corresponding monomolecular ‘free’ extractant analogues. However, some of the resins show acceptable extraction rates.
