| Abstract: |
| Aiming at the problems of complex chemical composition and dense structure of cellulose fiber materials， its poor adsorption performance and low application value when directly used to prepare anionic adsorbents， researchers have carried out in-depth research on improving the accessibility and reaction activity of hydroxyl groups on cellulose， cationic modification of cellulose and its adsorption performance on anionic substances. This paper mainly discussed the research progress of various pretreatment technologies and cationic modification technologies of cellulose fiber materials， expounded the mechanism of different pretreatment and cationization modification technologies in improving the reaction activity of cellulose hydroxyl group and the cationization reaction of cellulose fiber， and the adsorption performance of the as-prepared cellulose fiber-based anionic adsorbent was introduced as well. |
