摘　　要： 离子印迹技术是分子印迹技术的一个重要分支。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等优点,但离子印迹材料在完成吸附使命后从反应体系中分离困难。将离子印迹技术与磁性技术相结合制备的磁性离子印迹聚合物,不仅具有特定的分子识别位点,而且具有磁响应特性,在外加磁场作用下,容易分离回收。此文综述了近年来磁性离子印迹聚合物的研究进展状况,同时提出了目前该领域存在的问题和发展趋势。 Ion imprinting technology is an important branch of molecular imprinting technology.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.However,ion-imprinted polymers are difficult to separate from the solution.If ion imprinting technology is combined with magnetic technology,the prepared magnetic ion imprinted polymers not only have specific molecular recognition sites,but also have magnetic response characteristic,and can be separated and recovered easily under the extrinsic magnetic field.The research progress on magnetic ion imprinted polymer in recent years was reviewed in this paper.The problem and development trend in this area were also put forward.
