摘要:随着化工行业的发展,重金属离子污染日益加剧,严重威胁人体健康和生态安全。纳米纤维素作为一种含量丰富的可再生纤维素材料,具有优异的机械性能、高比表面积以及化学可修饰性等优点,在吸附领域应用前景广泛。综述了纳米纤维素及其吸附剂的制备方法,主要有直接改性和接枝改性等。同时也介绍了其在重金属离子吸附方面的应用进展。指出了纳米纤维素基重金属离子吸附剂存在的问题,并展望了纳米纤维素吸附剂可行的改性方向。
With the development of the chemical industry,heavy metal ion pollution has become increasingly serious.The pollution has seriously threatened human health and ecological security. Nanocellulose is a kind of regenerable cellulosic material with abundant mechanical properties,high specific surface area and chemical modification. It has wide application prospect in the field of adsorption. Some preparation methods of nanocellulose and its adsorbents were reviewed,including direct modification and graft modification. The application progress of heavy metal ions adsorption was also introduced. The existing problems of nanocellulose-based heavy metal ion adsorbents were pointed out,and the viable modification direction of nanocellulose-based heavy metal ion adsorbents was prospected.
