Abstract:

In this study, a series of Fe3-xTixO4 (0≤x≤078) were synthesized using a novel soft chemical methodThe synthetic Fe3-xTixO4 was characterized using XRD and FTIRThe results show that synthetic Fe3-xTixO4 has a spinel structure and Ti was introduced into its structureThe introduction of Ti into magnetite structure increases the amounts of hydroxyl (—OH) on the surface of Fe3-xTixO4Then, the synthetic Fe3-xTixO4 was used as absorbents for the removal of methylene blue (MB) from solutionThe experimental results indicate that with the increase of Ti in Fe3-xTixO4, the absorption of MB on Fe3-xTixO4was promoted remarkably and the absorption reached the equilibrium within 05 hour.
