在离子交换过程中，固定在离子交换树脂的离子在液相中被相等当量的其他离子替换，离子交换过程的速度由下列因素决定：
In the ion exchange process, ions immobilized in the ion exchange resin are replaced by other ions of xuanzhuang.89ix.comchengde.71ix.cngaonianji.07858.net shepiguan.89ix.combianyaqipd.37ix.com.cn laliji.07858.netequal equivalence in the liquid phase. The speed of the ion exchange process is determined by the following factors:
1）  从液体移动离子到树脂界面
1) Moving ions from Liquids to Resin Interfaces
2）  扩散进入离子交换树脂内部
2) Diffusion into the interior of ion exchange resin
3）  在树脂内部的移动
3) Moving inside the resin
4）  对官能团离子的吸附
4) Adsorption of functional group ions
