- Abstract
Ultra-fine titania powders were synthesized through sol-gel method. A surfactant-free nonaqueous approach was followed as a quite suitable alternative to surfactants using titanium tetrachloride and 2-ethyl hexanol as precursors. The prepared samples were calcined at different temperatures ranging from 500 °C to 800 °C. The crystal structure and thermal stability of metal oxide particles were studied using X-ray diffraction technique (XRD) and differential scanning calorimetry (DSC-TGA) respectively. The purity of powders was checked by infrared spectroscopy (IR) whereas the surface morphology was studied by field emission scanning electron microscopy (FESEM). The prepared titania samples were employed for the reduction of cyanide, BOD, COD, TDS, color and pH of industrial wastewater.
