| Title | The production of magnetic titanium dioxide particles and the degradation of dye | ||
| Keyword | |||
| Abstract | Taiwan used for various kinds of industrial dyes, a large proportion of the dyes was discharged into the sewage; most of the compounds are difficult to decomposition by microbial. TiO2 photocatalyst powders used to degradation of dyes, there are also having recovery problems. In this study, TiOSO4 and C12H28O4Ti are used as the basic compounds of photocatalyst. The sol-gel method was used, and FeCl3 and FeCl2 was use to modified the characteristic of TiO2. Iron particles coated by TiO2 was dehydration at 125 ˘J, then to calcined to 300 ˘J at furnace and, to production of magnetic TiO2. Finally, dye degradations of TiO2 photocatalytic reaction were conducted by the ultraviolet light. After the photocatalytic reaction, the recycling of TiO2 magnetism particles was assessment by magnets. The results showed the TiOSO4 coated particles with the benefit photocatalytic efficiency of dyes and the more sustained photodegradation abilities. The recycling of TiO2 magnetism particles was only 65 % ~ 75%. While the C12H28O4Ti coated particles with the less photocatalytic efficiency of dyes and the recycling of TiO2 magnetism particles was more than 95%. |
