中文摘要：

文章研究了黑碳吸附亚甲基蓝的动力学和热力学特性，探讨了温度、初始浓度、溶液pH值及转速等因素对吸附过程的影响。结果表明，吸附过程符合二级动力吸附方程，颗粒内扩散过程是影响吸附速率的主要控制步骤。用Freundlich方程能够更好地对吸附等温线进行拟合；吸附热力学研究表明：△H〉0，说明吸附为吸热过程；△G〈0，说明吸附质倾向于从溶液中吸附到吸附剂表面，反应过程是自发进行的；△S〉0，说明固，液相界面上分子运动更为混乱。

英文摘要：

This study intended to explore the application of black carbon to treating dyeing wastewater as an inexpensive adsorbent in place of activated carbon. According to the study of adsorption kinetics and thermodynamics of Methylene Blue, a water soluble dye, on black carbon, it is concluded that the adsorption is influenced by the factors including temperature, initial concentration, pH, rate of oscillation in compliance with the second-order kinetics. The adsorption isotherms fitted well to Freundlich equation.
