A special attention is currently focused on the recovery of Au, Ag, Pt, Pd and Rh from both primary and secondary sources. From the wide range of sorbents that have been used in this respect, the required selectivity is proved only by the chelating polymers containing donor N, O and S atoms in their functional groups. This work presents the recent published researches on this topic, pointing out the capabilities of chelating sorbents based on organic synthetic polymers for a sustainable development. The chelating sorbents are differentiated and reviewed according to their synthesis strategy and compatibility with synthetic and real matrices. First, an overview on the novel functionalized polymers and impregnated resins with good selectivity for the recovery of most valuable precious metals from synthetic leach solutions is given. Subsequently, the performances of these materials in the selective and preconcentrative recovery of Au, Ag, Pt, Pd and Rh from simulated and real leachates are discussed. The viability of an integrated approach for the determination of precious metals from simulated solutions by solid phase spectrometry is highlighted. The transposition of chelating polymers’ potential in challenging technologies for precious metal recovery-reuse-recycling needs further research on directions that are proposed.

具有宝贵吸附潜力的螯合聚合物可用于开发贵金属回收技术

目前特别关注从初级和次级来源中回收金、银、铂、钯和铑。从在这方面使用的各种吸附剂中，仅通过在其官能团中含有供体 N、O 和 S 原子的螯合聚合物证明了所需的选择性。这项工作介绍了最近发表的关于该主题的研究，指出了基于有机合成聚合物的螯合吸附剂的可持续发展能力。螯合吸附剂根据其合成策略以及与合成和实际基质的相容性进行了区分和审查。首先，概述了具有良好选择性的新型功能化聚合物和浸渍树脂，用于从合成浸出溶液中回收最有价值的贵金属。随后，讨论了这些材料在从模拟和真实渗滤液中选择性和预浓缩回收 Au、Ag、Pt、Pd 和 Rh 中的性能。强调了通过固相光谱法从模拟溶液中测定贵金属的综合方法的可行性。螯合聚合物在贵金属回收-再利用-再循环具有挑战性的技术中的转换潜力需要进一步研究提出的方向。
