Abstract
A solid particulate composition useful in extracting a lithium salt from aqueous solutions, the composition comprising lithium, metal atoms, oxygen atoms, and at least one anionic species (X) selected from halide, nitrate, sulfate, carbonate and bicarbonate, all in a framework structure, wherein said metal atoms are selected from at least one of oxophilic main group metal and oxophilic transition metal atoms, provided that, if the metal atoms comprise aluminum atoms, then at least 10 mol % of said aluminum atoms are substituted with at least one metal atom selected from said at least one oxophilic main group and oxophilic transition metal atoms, other than aluminum, and wherein said lithium is present in said composition in an amount less than a saturated amount in order to permit extraction of lithium salt. Methods for extracting and recovering a lithium salt from an aqueous solution by use of the above-described composition are also described.
