| Abstract: | Chelat fiber with amidoxime group, which is obtained from chemical modification of PAN fiber, is treated with ferric chloride to prepare anion-exchange fiber. The conditions of preparation influenced on fluorion exchange property of anion-exchange fiber are analyzed. The results show that the fiber has features of fast and large fluorine ion exchange capacity and easy regeneration. The highest exchange capacity is 30mg/g and exchange percent is over 90. |
