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 Fe 3O 4 with a spinel structure, and the binding of chitosan did not result in a phase change. IR analysi...
