Experimental results showed that the amphoteric ion exchange fibers consist of carboxyl and pyridine groups. Their total ion exchange capacity, the rate of cationic and anionic groups, and the morphology can be controlled by changing the type of monomers and the load ratio of acidic and basic monomers. In addition, the competitive adsorbability of the amphoteric fibers can be controlled by the structures of the fibers and adsorption conditions. When the feed content of pyridine monomer increases, the anionic exchange capacity and the ratio of anionic groups to total capacity of the resultant fibers increase. The morphology of the amphoteric fibers is synthesized with both the textures of poly-vinyl-pyridine and poly-acrylic (or methacrylic) acid which were produced in single component grafting system. The amphoteric fibers prepared possess high adsorption capacity for Cu2＋due to the coordination action of pyridine and carboxyl groups. When the contents of acidic and basic groups are close to each other, the coordination action for adsorption is enhanced.
