摘要
对现行的离子交换膜的选择透过性用顿南平衡解释提出质疑 ,在理论分析和实验的基础上 ,对离子透过膜的迁移途径提出了“空穴”模式 ,并对选择性建立了膜电位的孔道封闭理论 .
The donnan equilibrium,which is usually adopted to explain the selective penetrated property of ion exchange membrance is to be questioned.On the basis of theory analyzing and experiments,the“cavaties”model is presented to explain the migration path that the ions penetrate the membrance and membrance potential's pore closed theory is constructed explain the selective penetrated property of membrance.
