摘　　要：本文综合论述了纳米纤维素的理化结构和特点,以及利用表面改性和接枝共聚等改性方法制备用于净化工业废水中的染料和重金属离子的纳米纤维素基吸附剂。分析了近几年应用较多的几种主要的改性方法如羧基化、氨基化等,以及主要的吸附剂形式(如水凝胶和气凝胶等)。最后,展望了纳米纤维素基吸附材料用于水处理的发展方向。The physicochemical structures and characteristics of nanocellulose and nanocellulose-based adsorbents modified by surface modification and graft copolymerization for cleansing dye and heavy ions were reviewed.The commonly used main modification methods for nanocellulose-based adsorbents including carboxylation and amination,the forms of absorbents(e.g.,hydrogels,aerogels)were analyzed as well.Finally,the development direction of the nanocellulose-based adsorptive materials in wastewater treatment was prospected.
