【Abstract】 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.更多还原
