摘　　要：综述了重金属吸附剂高岭石的有机、无机改性方法研究进展,重点介绍了高岭石的无机改性方法(无机酸活化,过渡金属、金属氧化物、无机盐改性)对高岭石结构性质以及吸附性能的改善效果,并与同步改性的蒙脱石进行了比较,针对改性过程中仍然存在的一些不足,结合实际应用的要求,探讨了进一步研究中值得关注的问题。The research progresses in the modification of heavy metal adsorbent kaolinite are reviewed. The effects of the abio-modification processes （ such as inorganic acid activation, transition metal modification, metal oxide modification and inorganic salt modification and so on ） on the improvement of kaolinite structure, character and adsorption capability are introduced, and the abio- modified kaolinite are compared with the montmorillonite simultaneously modified by the same method. According to the shortcomings in the modification process and the requirements for its application, the problems in future research are discussed.
