A cellulose fiber was modified with Schiff base compound having the complexation ability of metal ions, and the modified cellulose fiber used as a metal ion adsorbent. The modified cellulose fiber was synthesized by reacting glycidyl methacrylate using diammonium cerium(IV) nitrate as a catalyst followd by reacting with bis-(2-pyridylmethylideneiminoethyl) amine as Schiff base compound having pyridyl groups. The obtained cellulose fiber, BPIEA-GMA grafted cellulose was characterized by SEM, IR, and XPS and used as a metal ion adsorbent. The adsorption behavior of metal ions on the BPIEA-GMA grafted cellulose was investigated. The examined metal ions except for Pb 2+ , Mn 2+ , and Rh 2+ were almost quantitatively adsorbed on the BPIEA-GMA grafted cellulose fiber. In addition, Pt 2+ and Pd 2+ able to adsorbed in hydrochloric acidic medium. The recovery of adsorbed metal ions except for precious metal ions from the adsorbent was successful, and the BPIEA-GMA grafted cellulose was able to use as a metal ion adsorbent by repeated twice. These results suggest that the modified cellulose fiber with Schiff base compound having pyridyl groups can be used as a metal ion adsorbents.
