Dialysis of single component solutions (oxalic acid, sodium hydroxide) and neutralisation dialysis of oxalic acid with sodium hydroxide were experimentally studied in a two-compartment batch cell. For this purpose, an anion-exchange membrane Neosepta-AHA was used. The transport of single components was quantified by the diffusion coefficient of the component as a function of its concentration in the membrane, while that of oxalic acid in the neutralisation dialysis experiments was quantified by the permeability coefficient of the membrane for oxalic acid. Moreover, the acceleration of the acid transport by an NaOH solution was evaluated by the enhancement factor based on the permeability coefficients.

在两隔室的间歇式电解槽中，对单组分溶液（草酸，氢氧化钠）的渗析以及氢氧化钠对草酸的中和渗析进行了实验研究。为此，使用了阴离子交换膜Neosepta-AHA。通过组分的扩散系数作为其在膜中浓度的函数来定量单个组分的迁移，而在中和渗析实验中通过草酸对膜的渗透系数来定量草酸的迁移率。此外，通过基于渗透系数的增强因子来评估由NaOH溶液进行的酸输送的加速。
