TiO2/蒙脱土复合催化剂对亚甲基蓝的吸附脱色研究

Study onAdsorptive Decolorized of Methylene Blue by TiO2/MMT Composite Catalysis

为了提高蒙脱土的吸附脱色性能,制备了TiO2/蒙脱土复合催化剂。并对亚甲基蓝的吸附脱色性能进行了研究。结果表明催化剂的投入量、吸附时间、煅烧时间对脱色效果有很大影响,在最佳条件下,亚甲基蓝的脱色率高达98.6%。

TiO2/MMT composite material was prepared to improve adsorptive decolorized capability of MMT.The adsorptive decolorized behavior of the prepared material to methylene blue was studied.The results indicated that the amount of catalyst,adsorption time and calcination time had a major effect on decolorized rate.The decolorized rate of the TiO2/MMT composite material to methylene blue reached up 98.6%under the optimized conditions.
