Qian, Z. (author)Electrodialysis (ED) is a membrane-based process in which ions are transported under the influence of an externally applied electrical potential. Ion-exchange membranes (IEMs) are key components in ED processes. There are two types of IEMs: (1) cation-exchange membranes (CEMs), which contain fixed, negatively charged groups, and (2) anion...doctoral thesis 2022
