摘要
探讨以粉煤灰为载体制备粉煤灰/TiO2复合物进行光催化降解亚甲基蓝试验。研究各种因素对亚甲基蓝光降解反应的影响,结果表明,当改性粉煤灰投加量为8g/L,亚甲基蓝浓度30mg/L,高压汞灯250W条件下,在60min左右,亚甲基蓝降解率达到了95%以上。
Research on Photo-Decolorization of Methylene Blue by compound Fly ash/TiO2,A variety of affecting factors on photo-Decolorization of Methylene Blue has been considered, results indicated that when fly ash quantity adds to about 8 g/L, Methylene Blue density 30 mg/L, under the 250 W mercury lamp shining, around 60 mins, the degradation rate of Methylene Blue has reached 95%.
