摘要
本文综述了通过氨基、羧基、硫醇基等官能团改性纳米纤维素以及纳米纤维素和其他材料复合,制备成2D膜材料和3D凝胶材料的方法及其性能,同时也介绍了其在水环境中去除重金属离子的应用进展,并对纳米纤维素基吸附剂的制备和应用进行了展望。
This review introduced the methods of preparing 2D membrane materials and 3D gel materials by using nanocellulose modified with amino groups,carboxyl groups,thiol groups and other functional groups,and also by the composite of nanocellulose and other materials.The properties of prepared 2D membrane materials and 3D gel materials were also presented.The application progress of removing heavy metal ions in water environment were discussed.It was also expected that the preparation of nanocellulose-based adsorbents should tend to be simpler,with more diversified applications,and more convenient and environmentally friendly regeneration.
