摘要
通过对离子交换膜表面 ζ电位和间歇通电时 ,电渗析隔室中离子变化的测定 ,建立了离子交换膜选择透过性的新理论 ,即孔道电位封闭及“空穴”传递理论 .
The Donnan equilibrium and the two electric layers theory have always been the classical theories to explain the selective property of ion exchange membrane for many years.But there are some problems for these two theories to explain the practical operation of electrodialysis especially in the DC electric field and continuous updating of solution.The ζ potential of membrane surface and the ion changes of electrodialytic compartments under batch operation were investigated in this paper.A new theory of potential close in the membrane pore and the'cavity'transfer was provided.
