摘要
回顾了离子印迹聚合物方面的主要研究内容和成果。由于离子印迹聚合物具有预定识别性,制备简单、价格低廉、稳定性好,对模板离子表现出较高的选择性和亲和性,在离子分离、富集以及传感识别等领域有着广泛的应用前景。介绍了离子印迹技术的原理,并依据模板离子种类的不同(主族金属离子、过渡金属离子、稀土金属离子、锕系金属离子、阴离子等),对各离子印迹聚合物的制备方法、吸附特性和应用性能进行了综述,并展望了离子印迹聚合物的发展方向。
Previous achievements in ion-imprinted polymers are reviewed.Ion-imprinted polymers have several outstanding advantages,such as predetermined recognition ability,relative easy and low cost preparation,high stability and excellent specific recognition ability for target ions,which can lead to potential applications in ions extraction and senor identification areas.The principle of ion imprinted technology is addressed.The varieties of template ions in imprinted polymer are introduced,including main group metal ions,transition metal ions,rare earth metal ions,actinide metal ions and anion.The preparation,adsorption performance and application of the ion imprinted polymer are then emphasized.The future development of template-ion is also prospected.
