| 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％.

| Abstract: | 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 by15mg/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%. |
