| 摘 要： | 以亚甲基蓝（MB）作为模拟染料废水，系统考察了活性炭（AC）对亚甲基蓝的吸附性能。计算得到了△G^0、△H^0、△S^0等几个热力学参数。实验结果表明：活性炭的吸附性能取决于吸附时间、废水pH值和废水温度。吸附行为符合二级反应速率方程所描述的规律和Langmuir吸附等温式。废水pH值的升高有利于提高最终吸附处理的效果。活性炭对亚甲基蓝的吸附是一个自发的、弱吸热的物理过程，温度的升高有利于吸附的进行。

| Abstract: | The adsorption capacity of methylene blue in wastewater by activated carbon was measured, thus having systematically studied the Property about the intermissive adsorption of methylene blue. The thermodynamic parameters such as △G^0、△H^0 and △S^0 have been calculated. The results show that the property of adsorption depends on adsorption time,pH and temperature. The adsorption of activated carbon for Methylene Blue fits well with the pseudo - second - rate equation and Langmuir isotherm model. The higher pH of dyestuff wastewater is, the better treatment effect can be obtained. Meanwhile, the adsorption of activated carbon for Methylene is a spontaneously and endothermically physical process, temperature increases being beneficial to adsorption. |
