| Abstract Scope |
Lithium is regarded as a critical raw material globally due to the expanding electric vehicle market. To meet battery supply demands, alternative lithium sources are being explored, with salt-lake brines emerging as a significant option. Electrodialysis (ED) offers a promising solution, providing high selectivity and productivity with reduced chemical reagent use and energy consumption. This study aims to evaluate the effect of common ions on lithium separation using ED with three different commercial membranes. Experiments were conducted in a 4-chamber reactor with feed solutions of equimolar chloride salts. The synthetic brine was designed to simulate brines. Our comprehensive investigation of various membranes also provides insights into process integration. Results from the synthetic brine experiments indicated the selectivity order as K > Na > Li >> Mg > Ca, with the final solution showing a higher ratio of lithium to divalent ions: Li/Mg and Li/Ca ratios were 5 and 3.5, respectively. |
