摘要
利用锯末半焦的吸附性能对亚甲基蓝溶液进行吸附实验,结果表明,pH为11,投加量为1.5g/L,温度40℃,吸附时间为60min,亚甲基蓝废水的初始浓度为15mg/L为吸附最佳条件.在此条件下锯末半焦具有良好的吸附效果,对亚甲基蓝的吸附行为符合Langmuir等温方程,脱色率可高达96.06%.
The adsorption experiments of sawdust semi-coke for methylene blue was made, the results show that, the optimum conditions were as follows： pH was 11, the dosage 1.5g/L, temperature 40℃, adsorption time 60min, initial concentration of methylene blue wastewater bylSmg/L. On these conditions, sawdust semi-coke has good adsorption effect for methylene blue, the adsorption behavior coincidence with Langmuir isothermal equation. The decolorization rate can be as high as 96.06%.
