摘要：
Two different protocols for magnetite and magnetite covered with dextran are presented. These products can be used in waste water treatment, especially as adsorbents for different metal ions. The synthesis methods, characterization of the final products and leaching test at different pH media were tested. The investigation methods for the characterization of the products obtained with different methods were scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The quantity of iron dissolved from magnetite was evaluated with flame atomic absorption spectrometry (FAAS).
