Research Progress on the Adsorption of Heavy Metal Ions by Modified Nanocellulose
With the rapid advancement of industrialization and urbanization,the issue of heavy metal pollution in water resources has been increasingly exacerbated,posing significant threats to both human health and ecosystems.This paper provides a detailed discussion on applying four principal methods for modifying nanocellulose for heavy metal ion adsorption:oxidation modification,esterification modification,etherification modification,and graft copolymerization modification.These methods significantly enhanced the adsorption capacity of nanocellulose for heavy metal ions by increasing the functional groups on its surface.Finally,future research directions for modified nanocellulose in heavy metal ion adsorption are explored,emphasizing the importance of selectivity,reducing costs,improving adsorption efficiency,and ensuring sustainability.
