采用酸性溶胶法制备了钛柱撑蒙脱石，研究了不同温度、pH值条件下样品对罗丹明B的吸附性能。结果表明，钛柱撑可以提高蒙脱石对水溶液中罗丹明B染料的吸附能力，吸附过程动力学符合准二级近似，为不可逆化学吸附，平衡吸附数据基本符合Langmuir和Freundlich吸附等温式；随着温度升高和pH值增大，钛柱撑蒙脱石对罗丹明B的吸附量下降，在温度298K左右，pH值低于3时吸附效果较好。

The adsorption of rhodamine B onto titanium pillared montmorillonite prepared by sol-acid method has been studied at different temperature and pH. The results indicate that the titanium pillaring can enhance the adsorption performance of rhodamine B in solution by montmorillonite. The adsorption kinetics, which followed pseudo-second order approximate model, is irreversible. The equilibrium adsorption data can better fit with both Langmuir and Freundlich adsorption isothermal equation. The adsorption capacity of rhodamine B onto titanium pillared montmorillonite decreases with the increasing of temperature and pH. The adsorption effect is better at temperature about 298 K and below pH 3.
