Abstract:

Cellulose is widely used as a natural bio-based material. The modification of cellulose and its application in adsorption have been the focus of research. In addition to introduce the basic structure of modified cellulose, this thesis summarizes the cellulose that modified by chemical modification and the high adsorption capacity of modified cellulose for various aquatic pollutants. We focus on the adsorption, adsorption mechanism of modified fiber and adsorption of metal ions and nitrogen and phosphorus in water. Moreover, this thesis also suggests that applying modified fiber material to soil could provide a comprehensive explanation for soil improvement and crop yield. Meanwhile, combining the modified cellulose with fertilizer improves the utilization rate of fertilizer and reduces the non-point source pollution caused by fertilization.

Key words: cellulose, chemical modification, aquatic pollutants, adsorption, natural bio-based material
