  • This study reports highly selective Li+Mg2+ separation via concentration gradient-driven transport using negatively charged membranes with high charge content. The separation mechanism involves selective partitioning of Li+ ions into the membrane and uphill transport of Mg2+ ions. Bench-scale diffusion dialysis experiments with model brine solutions demonstrate effective monovalent/divalent ion separation.
