摘要
采用溶胶凝胶法在不同条下制备出了纳米二氧化钛光催化剂,通过正交实验优化出了光催化剂的最佳制备条件,并研究了不同因素对甲基橙脱色率的影响。结果表明,不同pH值下,TiO2对甲基橙的脱色率影响不大;随着甲基橙初始浓度的增加脱色率下降;试验条件下TiO2的最佳投加量为0.1g/L。
Titanium dioxide（TiO2） photocatalysts were prepared by sol-gel method.The processing parameters of TiO2 were optimized by orthogonal experiment,and the influencing factors of decolourization efficiency for methyl orange were also investigated.The results indicated that the change of decolourization efficiency of methyl orange is unapparent under different pH values,decolourization efficiency presents a downward trend with the raise of initial concentration of methyl orange,and the optimal dosage of TiO2 is 0.1 g/L within the level of this experiment.
