The volume of ionic exchange is high in montmorillonite, in which ionic exchanging adsorption is mainly of high adsorption amount and lower adsorption energy barrier and high adsorption rate as well as less energy change of unit adsorption.

• 蒙脱土离子交换容量大 ,主要为离子交换吸附 ,吸附量较大 ,吸附能垒低 ,吸附速率大 ,单位吸附的能量变化不大。
