| 摘 要： | 制备了改性蛭石,并研究了其对Cu^2+、Zn^2+的吸附性能。结果表明:不论是单一体系还是竞争体系,Cu^2+的去除率均高于Zn2+的去除率。拟二级动力学模型更适用于描述Cu^2+、Zn^2+在改性蛭石上的吸附动力学过程。单一体系和竞争体系均可用Langmuir吸附等温方程进行描述。

| Abstract: | Modified vermiculite was prepared,and the performance of modified vermiculite for the adsorption of Cu^2+and Zn^2+was studied.The results showed that the removal rate of Cu^2+was higher than that of Zn^2+whether in single system or competitive system.The pseudo-second-order kinetics model was more suitable to describe the adsorption kinetics of Cu^2+and Zn^2+onto modified vermiculite.Langmuir adsorption isotherm equation could describe the single system and competitive system. |

| Keywords: | modified vermiculite adsorption Cu^2+ Zn^2+ dynamics isotherm |
