超声波对膨润土进行改性制得一系列改性土。研究结果表明：改性土对重金属离子Cu2+、Zn2+、Mn2+、Co2+的吸附好于原土，且超声时间越长吸附性能越好。与单一离子体系比较，超声改性土在混合离子体系中对各离子的吸附量均有不同程度的下降。超声改性土对四种金属离子的吸附顺序与重金属离子的水合能密切相关。

Bentonite has been modified by ultrasonic wave,for the preparation of a series of modified bentonites. The results show that:the adsorption for heavy metal ions Cu2+,Zn2+,Mn2+,Co2+by modified bentonite is better than that by raw bentonite. The longer the ultrasonic time is ,the better the adsorption capacity. The adsorption volume of ul-trasonic-modified bentonite in mixed ion system declines in different degrees ,when compared with single ion system. Modified bentonite is closely related to the adsorption sequence of the four kinds of metal ions and the hydration of heavy metal ions.
