摘　　要：采用离子交换法制备了鼠李糖脂(RL)-类水滑石(HTlc)纳米杂化物,并采用PXRD、FTIR、SEM、ICP、元素分析、比表面测定等方法对样品进行了表征。探讨了RL-HTlc纳米杂化物对对甲酚的吸附热力学行为。结果表明,RL-HTlc纳米杂化物对对甲酚的吸附量显著高于HTlc,且吸附等温线符合Linear方程,表明吸附为分配吸附。温度对吸附影响的结果说明吸附为放热、自发过程。Rhamnolipid（RL）-hydrotalcite-like compound（HTlc） nanocomposite was prepared by ionexchange method.The product was characterized by PXRD,FTIR,SEM,ICP,elemental chemical and specific surface area analyses.The adsorption behavior of p-cresol on RL-HTlc nanocomposite was investigated.The results indicated that the adsorption amount of p-cresol on RL-HTlc nanocomposite was much larger than that on HTlc.The adsorption isotherm of p-cresol on RL-HTlc nanocomposite can be well fitted with the Linear equation,implying a partitioning adsorption process.Along with the effect of temperature on p-cresol adsorption,an adsolubilization mechanism and an exothermic adsorption nature during adsorption process were revealed.
