摘要
利用污泥半焦的吸附性能对亚甲基蓝溶液进行吸附实验,并得出最佳条件.结果表明,反应温度为40℃,溶液pH值为11,半焦投加量为2g/L,吸附时间为30min,亚甲基蓝的质量浓度为15g/L时,污泥半焦对亚甲基蓝的脱色率可高达89.79%,污泥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.
The adsorption properties of sludge char to ethylene blue was investigated and the optimized condition was achieved. The results showed that decoloration efficiency sludge char to ethylene blue could be up to 89.79% when the temperature was at 40 ℃ ,the pH value was 11,the adsorption time was 30 min and the concentration of sludge char and methylene blue were 2 g/L and 15 g/L respectively. Sludge char had good adsorption abilities to ethylene blue and the adsorption behavior was in accordance with Langmuir isotherm equation.
