Sorption Properties of Magnetic Titanium Dioxide Composite
Original language description
Presented article is focused on the verification of the sorption properties of two forms of TiO2 (rutile and anatase) and their magnetically modified forms prepared by precipitation using microwave-assisted procedure. Batch sorption techniques were used to study the effect of (a) the contact time of adsorbate with sorbent (b) type of TiO2 particles (c) content of iron oxide nano- and micro-particles on the sorption process. Prepared sorbents were characterized and the Pb2+ ions concentration in solution after sorption was determined by AES-ICP. The stability of magnetic TiO2 particles was studied by the determination of the Fe concentration in solution after the sorption process using AAS-FA. The experimental data were described by both pseudo-first- and pseudo-second-order kinetic model. The results show that the pseudo-second-order kinetic model is the best corresponding kinetic model. Presence of magnetic iron oxides particles on the surface of sorbents lead to increase of the sorption rate, and increased the maximum amount of sorbed Pb2+ ions per mass in comparison with sorption on the both non-magnetic types of TiO2 particles. In addition, the magnetically modified TiO2 particles allow magnetic separation of the sorbents with already sorbed Pb2+ ions.
