 摘要： 研究了大孔树脂LS106对对叔丁基苯酚（4TBP）的吸附性能。在不同pH条件下测定了树脂对4TBP的吸附性能，随着pH值降低，树脂平衡吸附量增加。在温度为30315、31315和32315 K条件下分别测定了吸附平衡数据并用Langmuir和Freundlich吸附等温方程进行拟合。结果表明:4TBP在LS106型大孔吸附树脂上的吸附平衡符合Freundlich吸附等温方程，吸附过程属于可自发进行的物理吸附。分别采用准一级动力学模型、准二级动力学模型对实验数据进行模拟，结果表明，准二级动力学方程更适合描述LS106大孔吸附树脂对4TBP的吸附过程。

Abstract: The adsorption capability of macroporous resin LS106 for 4tertbutylphenol(4TBP) was studied. The adsorption of 4TBP on the macroporous resin were determined at different pH, and the equilibrium adsorption capacity of resin increased with  pH value decreasing. The adsorption equilibrium experiments were conducted under 30315，31315 and 32315 K. The adsorption data are correlated with the Langmuir and Freundlich isotherm equations. The results showed that Freundlich isotherm equation was better to describe the isothermal adsorption of 4TBP on the macroporous resin. The adsorption process is spontaneous physical adsorption. The experimental data were fitted to pseudofirst order model and pseudosecond order model respectively.The adsorption process of 4TBP on macroporous resin LS106 could be described better by pseudosecond order model.

Key words: 4tertbutylphenol; macroporous resin LS106; adsorption
