摘　　要：随着工业化和城市化的快速发展,水资源重金属污染问题持续加剧,威胁着人类和生态系统健康。详细讨论了四种主要的改性纳米纤维素的方法在重金属离子吸附中的应用,包括氧化改性、酯化改性、醚化改性和接枝共聚改性。这些改性方法通过增加纳米纤维素表面的官能团,显著提高了其对重金属离子的吸附能力。最后,文章对改性纳米纤维素在重金属离子吸附方面的未来研究方向进行了展望,强调了选择性、降低成本、提高吸附效率和可持续性的重要性。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.
