Abstract:

Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of these nanoparticles were found to be about ۱۵ to ۳۵ nm. Adsorption studies of heavy metal ions were carried out by batch experiments. pH, temperature, contact time and adsorbent dose were studied as the factors that effecting the adsorption of heavy metal ions on the surface of magnetic nanoadsorbents. The optimized values for pH, temperature, contact time and adsorbent dose were ۱۰, ۳۱۳ K, ۵۰ min and ۰.۲ g, respectively. Also the maximum amounts of removal efficiency for pb۲+ and Cu۲+ ions was ۹۸%. Thermodynamic parameters reveal the feasibility and spontaneity nature of the adsorption process and the adsorption kinetics of pb(II) and Cu(II) ions follow a pseudo-second-order kinetic model.
