新型螯合纤维在金属离子富集分离中的应用

摘要

In recent years, chelating ion-exchange fiber has been paid more and more attention in the field of scientific separation research, for its use of extraction, separation and analysis of metal ions. Chelating ion-exchange fiber has strong adsorption and excellent adsorptive selectivity of metal ions. It can be used for recycling, enrichment, separation of metal ions, such as radioactive metal ions, precious metal ions, transition metal ions and rare earth metal ions, etc. In order to improve the adsorption and selectivity of chelating ion-exchange fiber, many chelating ion-exchange fibers of new structure have been prepared recently. This paper reviews the preparation and adsorption performance recent new chelating ion-exchange fibers. And the development prospect is also presented.%近年来,螯合纤维在金属离子的提取、分离、分析等方面的研究成为分离科学领域的研究热点。螯合纤维对金属离子具有很强的吸附性和高的选择性,可以用于放射性金属、贵金属、过渡金属和稀土金属离子的回收、富集和分离等方面。为了进一步提高螯合纤维的吸附性和选择性,众多学者对如何制备出性能优良的螯合纤维进行了大量的研究工作。综述了近年来新型螯合纤维的制备和吸附性能。
