| 摘 要： | 研究了XC-72型炭黑材料对亚甲基蓝的吸附。实验结果表明：亚甲基蓝在XC-72上的吸附在3h达到平衡，吸附行为符合拟二级动力学方程和Langmuir方程。当温度为20％，pH为6．5时，最大吸附量为40．11mg·g^-1。溶液pH值的升高有利于提高吸附效果。XC-72对亚甲基蓝的吸附是一个自发熵增的吸热过程。

| Abstract: | The adsorption of methylene blue on XC-72 carbon was investigated. The results showed that the adsorption equilibrium time of methylene blue is 3 hours. The adsorption of methylene blue on XC-72 carbon fits well the pseudo-second-order rate equation and Langmuir isotherm model. While pH is 6.5,the maximum adsorption capacity was 40.11 mg·g-1 at 20℃ . The adsorption capacity improved with the pH improving. The adsorption of methylene blue is a spontaneous,entropy increasing,endothermic process. |
