Dynamics of deionization of electrolyte solution by sorption on aerogel electrodes is studied in the work on the basis of mathematical modeling. The processes of substance transfer by solution flow, diffusion and sorption in pores are taken into account. It is shown that for the correct description of the physical processes occurring in the deionizer under the potential difference on the electrode plates it is necessary to take into account the finite size of the hydrated ions and the change of the Stern layer on the surface of pores during substance diffusion. The change of the Stern layer is studied on the basis of mathematical modeling. The examples of simulation of the deionization process in a cyclic mode for different values of physical parameters are given.

考虑 Stern 层厚度变化的电容去离子模拟

在数学建模的基础上，研究了在气凝胶电极上吸附对电解质溶液的去离子动力学。考虑了通过溶液流动、扩散和吸附在孔隙中的物质转移过程。结果表明，为了正确描述电极板上电位差下去离子器中发生的物理过程，需要考虑水合离子的有限尺寸和孔隙表面Stern层的变化。在物质扩散过程中。在数学建模的基础上研究了Stern层的变化。给出了在不同物理参数值下循环模式下模拟去离子过程的例子。
