The Preparation of TiO₂ Nanoparticles and Wastewater in Paper Mill Treatment with TiO₂ Nanoparticles

Abstract:

Nano titanium dioxide particles were synthesized by drolysis of TiCl₄ through the phase thransfer and pH of the system is adjusted by Na₂CO₃ At the same time, the particles were characterized by the Transmission Electronic Microscope(TEM) and X-Ray Diffraction(XRD).As the result, it is shown that the TiCl₄ solution was transformed from n-octyl alcohol to deionized water phase and reacted with the deionized water at 55°C, the precursors of nano-TiO₂—Ti(OH)₄ was dried for 6 hours under vacuum at 70°C,then calcined 3 hours in muffle furnace at 400°C.At last, the TiO₂ nanoparticles which is uniform distribution, weak agglomeration was synthesized. In addition, wastewater in paper mill treatment with TiO₂ nanoparticles was studied by experiment. It is shown that suspended substance and COD in wastewater were brought dwon largely. The mechenism that wastewater was treated is disscussed.
