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

Abstract:

Article Preview

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.
