“…At such a high salinity and high Mg 2 þ /Li þ ratio, above technologies are not viable. Nanofiltration processes [13] have been investigated as the potential technologies for the extraction of lithium from the salt lake brine, but failed due to the precipitation of salt in the membrane module. Solvent extraction [14] and more advanced supported liquid membranes (SLMs) [15,16] are more attractive for the lithium extraction because of the high efficiency and more importantly the higher selectivity.…”

“…In Figure c, the permselectivitues of rGO‐SDDS‐rGO#4 are 1.19 (Na + /Li + ), 5.27 (Li + /Mg 2+ ), and 4.72 (Li + /Ca 2+ ), respectively (results of other rGO‐SDDS‐rGO membranes are shown in Figure S13 in the Supporting Information). The selectivity efficiency and permselectivity values for Na + /Li + , Li + /Mg 2+ , and Li + /Ca 2+ can be evaluated by the ion hydration energies Δ G of Li + , Na + , Mg 2+ , and Ca 2+ , which are 636, 454, 2555, and 1615 kJ mol −1 , respectively (Figure S14 and details in the Supporting Information) . When ions penetrate through the rGO‐SDDS‐rGO#4 membrane, the hydration ions need the de‐hydration energy to ensure the ions can enter the interlayer spacing, which is about 0.48 nm.…”

Graphene, a 2D sp2‐hybridized carbon sheet is a hot topic in the fields of materials science and chemistry. Here, a symmetrical multilayer architecture of graphene is designed by grafting of sulfonated 4,4′‐ diaminodiphenyl sulfone (SDDS) with the ample sulfonate groups and tunable interlayer spacing to exhibit the Li+ extraction from ionic mixtures with Na+, Mg2+ and Ca2+. Under the application of an electric field, the selective separation of cations can be achieved by controlling the flow channels of negatively charged ions (≈0.48 nm) during the synthesis of rGO‐SDDS‐rGO membrane. The result shows that the ion selectivity of the rGO‐SDDS‐rGO membrane is Na+ > Li+ > Ca2+ > Mg2+ and the absolute separation efficiency values of Li+/Mg2+ and Li+/Ca2+ are as high as 85.32 and 80.81%, respectively.

Despite the prosperity of membrane technology, the separation efficiency for Mg 2+ /Li + mixture is still far from satisfactory. Herein, a novel thin-film nanocomposite (TFN) membrane was developed by loading polyhydroxylated fullerene (PHF) via interfacial polymerization. The effects of the PHF dosages on the as-developed membranes were investigated comprehensively by XPS, SEM, AFM, contact angle measurements, as well as nanofiltration tests. The results revealed the TFN membrane containing 0.01% (w/v) PHF exhibited the optimum performances. The membrane showed a pure water flux of 6.7 LÁm −2 Áh −1 Ábar −1 and salt rejections with the order of Na 2 SO 4 (95.6%) > MgSO 4 (93.6%) > MgCl 2 (89.9%) > NaCl (22.6%) > LiCl (16.3%). The membrane not only presented a separation factor of 13.1 in separating Mg 2+ /Li + mixtures, but also demonstrated excellent antifouling ability, which enables membrane regeneration without operation break, suggesting its great potentials in the recovery of Li + from brine or seawater.
