Study on β-cyclodextrin Grafting Cellulose Fiber Enriching Heavy Metal Ions

In this paper, a kind of new cellulose fiber called β-cyclodextrin gr afting cellulose fiber is prepared. On the basis of preparation, its function i n enriching heavy metal ions is also discussed. The experiments show that cellul ose fiber reacts with epichlorohydrin during preparation, the molecular structur e of cellulose is not destroyed after being grated, and β-cyclodextrin grafting cellulose fiber has strong function in enriching meavy hetal ions(Cu2+ and Cr3+ ). The β-cyclodextrin can be applied to environment protecting industry.
