摘　　要：通过化学改性向纤维素分子中引入新的功能基团是一种十分有效的,可以赋予纤维素新的功能,例如吸附性能的方法。与一般的纤维素吸附剂相比,纳米纤维素吸附剂的尺寸更小、表面积更大,因此吸附性能较强,是近几年纤维素科学的研究热点。综合介绍了纳米纤维素吸附剂的研究进展,包括纳米纤维素晶体吸附剂、纳米纤维素复合物吸附剂和纳米纤维素纤维吸附剂,并简述了纳米外纤维素吸附剂的再生研究。The introducing of functional groups onto the cellulose molecules by the way of the chemical modification was an effective way of inventing new cellulose functional properties, for example the adsorption property. Comparison with the usual cellulose adsorbents, the nanocellulose adsorbent had an excellent adsorption performance because of the smaller size and bigger surface, which was a hotspot of cellulose science and technology in recent years. The progress of the nanocellulose adsorbents were comprehensively and discussed, including the nanocrystalline cellulose adsorbents, the nanocellulose composites adsorbents, and the cellulose nanofiber adsorbents. The recycling research of the nanocellulose adsorbents was also introduced.
