SYNTHESIS OF HIGH PURITY TiO2 NANOPARTICLES FROM Ti(SO4)2 IN PRESENCE OF EDTA AS COMPLEXING AGENT
TiO2 nanoparticles were synthesized by a homogeneous controlled precipitation method using industrial titanium sulfate (Ti(SO4)2). The obtained powders were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR) and ICP plasma spectrometer. EDTA was used as complexing agent to improve the purity and the formation of TiO2 nanoparticles. Experimental results indicated that the high-purity TiO2 nanoparticles were 20 nm in mean size and nearly monodispersed.
