摘要

纳米纤维素材料（cellulose nanomaterials，CNs）作为一种可再生材料，具有比表面积大、高结晶度、高强度、高杨氏模量、高表面活性、化学性质稳定等优异性能。纤维素作为天然高分子材料，在清除水体重金属离子中具有较好的应用的价值，因此本文对纤维素的改性及其吸附重金属的应用进行了综述。首先简要地介绍了纳米纤维素的结构与命名方法；其次，对纳米纤维素的改性（即小分子改性与高分子改性）进行了详细的介绍，并重点阐述了改性纳米纤维素基材以粉末、凝胶（包括水凝胶与气凝胶）两种不同的形态通过吸附清除水体重金属离子的应用研究。最后，对改性纳米纤维素基水吸附材料存在的优缺点进行了探讨，并指出了该材料在生产和应用过程中还需解决的问题。

Abstract

As a renewable material

cellulose nanomaterials (CNs) have good performance for removal of the metal ions from wastewater dut to their excellent surface area

high crystallinity

high strength

high Young's modulus

high surface activity

and chemical stability. So

in this paper the modifications of cellulose and its application to adsorb heavy metal ions were reviewed. Firstly

the structure and naming method of nanocellulose are briefly introduced. Secondly

the modifications of nanocellulose (ie

small molecule modification and polymer modification) are introduced respectively

and the modified nanocellulose-based materials are focused on describing in application of removing water metal ions by adsorption in two different forms of powder and gel (including hydrogel and aerogel). Finally

the advantages and disadvantages of the modified nanocellulose-based absotbent materials were discussed

and the problems that the materials need to solve during the production and application process were pointed out.
