| 摘 要： | 以天然麦壳为吸附剂,研究了时间对麦壳吸附水溶液中亚甲基蓝(MB)的影响.随着吸附时间的增加,麦壳对MB的吸附量增加,60 min后吸附趋于平衡.根据准二级动力学的非线性形式和3种线性形式,采用最小差方和的方法,用线性回归分析和非线性回归分析方法,得到了准二级动力学方程的参数.结果表明,线性分析和非线性分析都可用于预测时间对麦壳吸附MB的影响.

| Abstract: | The effect of contact time on methylene blue(MB)adsorption onto wheat husk was studied.The adsorptive quantity of MB on wheat husk increased as the contact time increased and the equilibrium was nearly reached after 60 min.The data were fitted to pseudo-second order kinetic model using linear and nonlinear regressive analysis and the relative parameters were obtainedr,espectively.The error analysis was also performed.Present investigation showed that the linear and nonlinear methods were both suitable to pr... |
