Abstract：In this study, the natural cellulose fibers are chosen as template and the anion adsorbent cellulose-g-PDMAEMA is synthesized for arsenic removal. The cellulose fibers were surface modified by graft-polymerization of(N,N-dimethyl aminoethyl methacrylate) (DMAEMA) initiated by Ce4+. The adsorbent was characterized by Field Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Infrared Spectroscopy(FT-IR) and elemental analyzer. And the adsorption behavior was evaluated by both batch and column experiments. The results indicate that the adsorbent has a high efficiency in the removal of arsenite and arsenate from aqueous solutions.
