摘要:

纤维素作为天然生物基材料来源广泛,纤维素的改性及其在吸附方面的应用一直作为研究的热点。笔者介绍了纤维素基本结构,综述了纤维素化学改性方法以及改性纤维素对水体污染物吸附能力的提高。重点从改性纤维素良好的吸附性、吸附机理以及对水体中金属离子和水体中氮磷的吸附性展开叙述。提出了改性纤维素可应用于土壤当中,以期为土壤改良、作物高产提供全面的科学解释;同时改性纤维素可与肥料相结合,提高肥料利用率减缓因施肥造成的面源污染等问题。

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
