ABSTRACT

The paper aims to present the synthesis, characterizations and efficiency tests for Cd and Zn removal from waters by help of iron nanostructured materials. Iron nanostructured materials such as magnetite were synthesized by classical co-precipitation technique, while for the characterization were used X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive X-ray spectra (EDS) methods. In order to establish the efficiency removal, atomic adsorption spectrometry was used. The efficiency tests indicated removal efficiencies of about 75% for Zn and 50 % for Cd removal. The adsorption equilibrium was achieved within 30 minutes for Zn(II) and Cd (II). The results indicated that the iron oxide nanoparticles could represent a valuable material for heavy metals removal from waters.
