以蒙脱石为吸附剂，分别和同时去除阳离子和阴离子染料。当染料单独存在时，仅对阳离子染料有较好的去除效果。实验数据符合准二级动力学模型，吸附行为符合Langmuir模型，表明阳离子染料在该树脂上的吸附是一个单层覆盖的电荷限制吸附过程。用分子模拟方法分析了污染物在层间的分子排列。由于阳离子染料和阴离子染料共存，因此阳离子染料和阴离子染料都可以被去除。通过平衡实验、XRD和分子动力学模拟，研究了该条件下吸附剂对阴离子染料的吸附机理。实验结果表明，混合废水中阴离子染料的去除符合Freundlich模型，由于阳离子染料在层间形成有机相，阴离子染料的去除机理为疏水相互作用。
Montmorillonite was employed as adsorbent to remove cationic and anionic dyes respectively and simultaneously. When the dye present singly, it only had a good effect to cationic dye removal. The experimental data well fitted to pseudo-second-order kinetic model, and the adsorption behavior followed the Langmuir model revealed that cationic dye adsorption was a monolayer coverage and charge-limited adsorption process. Molecular arrangement of the contaminants in the interlayer were analyzed by molecular simulation. As the cationic and anionic dyes co-exist, both cationic and anionic dyes could be removed. The adsorption mechanism of anionic dyes, under the circumstances, were investigated through equilibrium experiment, XRD and molecular dynamics simulation. The experimental data showed that anionic dyes in mixed wastewater were fitted Freundlich model well and the mechanism of anionic dyes removal was trapped by hydrophobic interaction on account of organic phase formed by cationic dyes in the interlayer.
