摘要： A method for selectively removing sodium or potassium from an alkaline lithium-containing aqueous solution, the method comprising: (i) contacting the alkaline lithium-containing aqueous solution with a hydrophobic solution comprising: (a) an aqueous-insoluble hydrophobic solvent, (b) a protic ionic liquid of the formula X−Y+, wherein X− is a conjugate base of a superacid and Y+ is a protonated cation, and (c) at least one of lipophilic sodium-selective and potassium-selective complexing ligands, wherein the contacting step results in selective complexation with and removal of sodium and/or potassium ions from the lithium-containing aqueous solution into the hydrophobic solution along with simultaneous abstraction of a proton from Y+ to form Y; and (ii) separating the aqueous solution from the hydrophobic solution, wherein, in some embodiments, X− is a bis(sulfonyl)imide and Y+ is a protic ammonium species. The method may further include stripping sodium and potassium ions from the hydrophobic solution and regenerating Y+.

摘要： A lithium extraction composite comprising: (i) a porous support and (ii) particles of a lithium-selective sorbent material coated on at least one surface of the support, wherein the support has a planar membrane, fiber (or rod), or tubular shape. A method for extracting and recovering a lithium salt from an aqueous solution by use of the above-described composition is also described, the method comprising (a) flowing the aqueous source solution through a first zone or over a first surface of the lithium extraction composite to result in selective lithium intercalation in the lithium-selective sorbent material in the first zone or first surface; and (b) simultaneously recovering lithium salt extracted in step (a) from said lithium-selective sorbent material by flowing an aqueous stripping solution through a second zone or over a second surface of the lithium extraction composite in which lithium ions from the first zone or first surface diffuse.
