纤维素吸附剂相关进展

随着工业化进程加快,人类活动加剧,各种环境问题日益突出,水污染首当其冲。工业生产和日常生活排放的有毒重金属离子和有机废物等造成了严重的水体污染。因此,开发出一种实用有效的吸附剂迫在眉睫。研究发现,天然纤维素可以用作吸附剂,通过化学改性可以显著增强其吸附性能。本文主要概述了纤维素吸附剂的物理化学性质、吸附机理及化学改性研究。从现有文献发现纤维素吸附剂具有十分广阔的应用前景,但工业化生产应用还存在一定的困难,需做进一步的研究。

Progress in Cellulose Adsorbent

Since industrialization,a variety of pollutions from human activities have increased greatly than before in China.As we know,China is facing aserious water pollution challenge especially.The water was infected with toxic materials from industrial production and daily life,such as heavy metal ions and organic waste.Therefore,it is urgent to draw up and introduce an effective and practical adsorbent.Depending on a recent study,we found that cellulose is abundant in nature,and its adsorption effect is very obvious.Meanwhile,adsorption capacity can be enhanced with chemical modification.Given this,in this thesis,the physical chemical property of cellulose,adsorption mechanism as well as chemical modification will be summarized.From the present articles,we can discover that the application of cellulose adsorbent enjoys great potential and promising prospects.However,industrial applications of cellulose should be explored further.
