Abstract:

以剩余污泥为原料,氯化锌为活化剂制备污泥活性炭。研究了初始pH值、吸附温度及离子强度对污泥活性炭吸附亚甲基蓝效果的影响。采用高分辨电子扫描电镜(SEM)和氮吸脱附曲线对污泥活性炭进行了表征。结果表明,随着pH值的升高,吸附量增大,碱性条件下最好。在15~55℃的范围内,亚甲基蓝的吸附量先增加后降低,温度为35℃时吸附量达到最大值。加入氯化钠后的污泥活性炭的吸附能力变弱,但随着离子强度的增大,变弱的强度减少。污泥活性炭以中孔为主和污泥活性炭具有不规则结构,预示着污泥活性炭较高的吸附能力。污泥活性炭对亚甲基蓝的吸附符合Langmuir等温吸附方程。污泥壳活性炭对亚甲基蓝的吸附符合二级反应动力学方程反应特征。
