螯合吸附分离功能纤维的研究进展

Progress in Research on Functional Fibers for Adsorption and Separation by Chelating

螯合纤维是一类能与金属离子形成多配位络合物的纤维状吸附功能材料,是近年来发展起来的一种新型离子交换纤维,具有吸附选择性高、易洗脱、容易再生等优点。综述了近年来螯合纤维的制备方法及种类,对其螯合机理进行了探讨,概括了该纤维的应用范围并指出了其应用前景。

Chelating fibers are a novel fibrous adsorbents, which contain abundant functional groups and can form multi-donor ligand with metal ions. This novel fibrous adsorbents have greater adsorption/ desorption rate and larger adsorption capacity than other adsorbents. This paper have overviewed recent progress on their synthesis methods, varieties , mechanisms and the application to inorganic analysis and water purification. Finally, some proposals are provided for its prospect in application.
