Since industrialization

a variety of pollutions from human activities have increased greatly than before in China. As we know

China is facing a serious 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.
