Highly efficient lithium extraction from magnesium-rich brines with ionic liquid-based collaborative extractants
ns. The results demonstrated that the system 1-(2-hydroxyethyl)-3-methylimidazolium bis(trifluoromethylsulfonyl)imide + trioctyl phosphate ([HOEMIM][Tf2N] + TOP) was considered as the best extractant, [...] Selective extraction of Li+ from high Mg2+/Li+ ratio brines with ionic liquid (IL) based collaborative extractants was investigated by experiments, thermodynamic analyses, and quantum chemical (QC) ca [...] with the very high extraction efficiency of Li+ (ELi+≈83%) and separation selectivity of Li+/Mg2+ (≈742), which is higher than any known report from the open literature. The thermodynamic model ePC-SAFT …
