a Schematic diagram illustrating different ions passing through or rejected by ordered LiOH-Am7CD-0.05 TMC membranes. b–d Observed rejection versus (b) ionic diameter46, (c) hydrated diameter46, and d molar Gibbs energy of hydration47 of different cations (with Cl- as the counter-ion in the solution). Filtration tests were performed using a series of single-salt feed solutions with a concentration of 2000 ppm. The dash line is simply a guide for the reader. Error bar standard deviation.
