摘    要：根据离子在外电场作用下同时发生电迁移传质和浓度扩散传质的特性,建立了电渗电解脱盐过程的数学模型,并用实验对数学模型进行了验证.实验结果表明,在高电流密度下,实验测定浓度值与数学模型的理论值吻合；在低电流密度下,实验值偏离理论值 .

Abstract: Mathematical model for desalination by electrolysis-electrodialysis was established on the basis of electromigration and concentration diffusion. The model was tested by experiments. The experimental results showed that data determined by experiments were in agreement with those by the mathematical model at large current density, but deviated from them at small current density.
