综述了近年来吸附精制废润滑油的研究进展并对吸附精制的作用机理进行介绍；吸附过程是包括阳离子交换、π络合吸附、酸碱中和、离子-偶极作用等多种机制共同产生的效果，这对制备效果好的多功能吸附剂有重要意义；最后对今后研究重点及对改性水滑石处理废润滑油的可行性进行了展望。

The latest research progress in refining spent lubricating oils through adsorption is reviewed and the refining mechanism is introduced.It is concluded that the adsorption process includes cation exchange,π complex adsorption,acid-base neutralization,ion-dipole interaction,etc.The effects of these mechanisms produce great significance to the preparation of a good multi-functional adsorbent.Finally,the future research focus is forecasted and the feasibility of using modified hydrotalcite to treat spent lubricating oil is expected.
