论文摘要
已经研究了用于通过实验和理论建模的电透析（ED）和反向电透析（红色）的离子交换膜厚度的影响。通过开发基于Nernst-Planck理论的二维模型，我们从理论上发现，仅降低膜厚度效益过程性能，直到一定值下降，低于该性能下降。对于ED，可以在10-20微米的范围内确定最佳厚度，而对于红色，对于厚度的三倍，发现最大功率密度。模型计算与一系列具有相同化学成分和厚度在10-75微米的厚度的均匀膜收集的实验数据很好地比较。我们的结果表明，膜应尽可能薄的经典图片（只要它们保持不含针孔且在结构上稳定）是不足的，并且必须被更准确的理论框架所取代。
The effect of the thickness of ion exchange membranes has been investigated for electrodialysis (ED) and reverse electrodialysis (RED), both experimentally and through theoretical modeling. By developing a two-dimensional model based on Nernst-Planck theory, we theoretically find that reducing the membrane thickness benefits process performance only until a certain value, below which performance drops. For ED, an optimum thickness can be identified in the range of 10-20 microns, while for RED the maximum power density is found for membranes that are three times as thick. Model calculations compare well with experimental data collected with a series of homogeneous membranes with the same chemical composition and a thickness in the range of 10-75 microns. Our results show that the classical picture that membranes should be as thin as possible (as long as they remain pinhole-free and structurally stable) is insufficient, and must be replaced by a more accurate theoretical framework.
