Fig. 2: Selectivity for lithium extraction from brines.

Lithium and sodium concentration percentage at a 1:1 and b 1:77 concentration ratio feed solution; c lithium selectivity over sodium with different feed solution concentration ratios. Metal ion concentration percentage with synthetic geothermal brine A (d) and synthetic geothermal brine B feed solution (e); f lithium selectivity over sodium, calcium, and potassium with two synthetic geothermal brines. Error bars indicate the standard deviation of duplicate measurements using different electrodes. g a photo of synthetic geothermal brine B feed solution.
