REGENERATION OF TWO-LAYERED CRYSTALLINE LITHIUM ALUMINATE USING LI(+) AQUEOUS SOLUTION

摘要

Ion exchange resins in the base form (e.g., DOWEX MWA-1-OH ion exchange resin) which contain crystalline Al(OH)3 (e.g. gibbsite, and/or bayerite, and/or norstrandite) are treated with hot, concentrated LiX aqueous solutions (where X is anion) to prepare 3-layer crystalline LiX.2Al(OH)3.nH2O in the resin.
