TiO2-based sorbent of lead ions
Original language description
The non-magnetic TiO2 powder and magnetically modified TiO2 powder were employed for the sorption experiments. FeSO4.7H2O was used for synthesis of magnetically responsive TiO2. The non-magnetic and prepared magnetic materials were characterized by scanning electron microscopy and X-ray diffraction methods. The particle size and specific surface area were determined. A detailed study of the adsorption process performed using batch adsorption experiments was carried out with various concentrations of lead ions and contact time. A flame atomic absorption spectrometer was used for determination of Pb2+ ions concentration in solution. Adsorption process has been modeled by the Langmuir and Freundlich isotherms using linear and non-linear regression. The results showed that the adsorption of Pb2+ ions on the magnetic and non-magnetic TiO2 particles occurred in a monolayer. Presence of magnetic iron oxides particles on the surface of sorbents increased the adsorption rate, and increased the maximum amount of adsorbed Pb2+ ions per mass in comparison with adsorption on the non-magnetic TiO2 particles. The magnetically modified TiO2 particles allow magnetic separation of the sorbents with already adsorbed ions of pollutants.
