Ethylenediamine-modified magnetic chitosan (EMMC) complex was developed as a novel magnetic adsorbent for the removal of uranyl ions. XRD spectrum indicated that the magnetic particles were pure Fe3O4 with a spinel structure, and the binding of chitosan did not result in a phase change. IR analysis demonstrated that Fe3O4 particles were successfully bounded by chitosan and more amino groups appeared in the EMMC samples. EMMC was found to be quite efficient to adsorb uranyl ions at pH 2-7. Equilibrium was established within 30 min, and the kinet...
