| Abstract: | Methyl red in aqueous solution is degradated by supported nano-TiO2 or TiO2.The result showed that nano-TiO2 was better than TiO2 on degradation of methyl red,the optimum decoloration rate reached 99.2%,joined 3- 5 mL ClO2 or H2O2 and 3 slides supported nano-TiO2 of 1.0 mg/cm^2 in 150 mL methyl red solution,after UV-illuminating 60 minute. |
