Research progress on ion imprinted polymer and application towards metal ion recognition

金属离子的识别和选择性研究仍是当前水体金属离子污染分析中一大挑战。离子印迹材料具有制备简单、结构稳定、识别性强、吸附速率快、吸附容量大和易回收等特点,在离子分离、富集和传感识别等领域受到广泛的关注。在过去的研究中,有两方面重点内容始终贯穿离子印迹材料的发展历程。一是印迹材料的制备过程的优化,二是识别性能以及识别机理的研究。本文按照时间轴的顺序对离子印迹材料的发展进行综述,并重点归纳了制备过程和识别机理的研究进展。另外对现阶段离子印迹材料在识别吸附重金属中的应用进行了总结和展望。

Selective recognition of metal ions was a real challenge on a large range of applications in the analytical of metal ions pol-lution. Due to the advantages such as simple preparation process,high chemical stability,outstanding ability of adsorption capacity and selectivity,fast adsorption kinetics and excellent reproducibility,ion imptinted polymers（ IIPs） had gained a lot of attention in preconcentration and sensors. The optimizing of imprinting process and recognition mechanism were always big issues in research progress. The aim of this article was to give a review of research on ion imprinted polymer according to imprinting process and recog-nition mechanism. In addition,we made a summary and prospects of applications on selective recognition metal ions of ion imprinted polymer.
