| 摘 要： | 利用四钛酸钾晶须作为吸附剂,研究了亚甲基蓝在其上的吸附行为,考察了吸附体系pH值、吸附剂用量、吸附时间对其吸附效果的影响.实验结果表明,四钛酸钾晶须对亚甲基蓝有较强的吸附力,得到的吸附等温线能较好的符合Freundlich方程,其R2都能达到0.991以上,吸附动力学可以用拟二级动力学模型描述.在碱性范围内四钛酸钾晶须... |

| Abstract: | Equilibrium adsorption isotherms for the removal of methylene blue from aqueous solution using K2Ti4O9 whiskers were investigated.Equilibrium data were mathematically modeled using Langmuir and Freundlich adsorption models to describe the isotherm at different temperatures,and isotherm constants were determined.Results indicated that Freundlich adsorption was found to best fit the experimental data of methylene blue,with R2 more than 0.991.Adsorption kinetics could be well described by pseudo-second order k... |
