Title:
METHOD FOR RECOVERING POLYOXOANION COMPOUND
Document Type and Number:
WIPO Patent Application WO/2011/062303
Kind Code:
A1
Abstract:
A method for recovering polyoxoanion compounds from an aqueous solution containing polyoxoanion compounds has the following steps. Step (1): Mix an organic solvent capable of forming a complex with the polyoxoanion compound and the aqueous solution, resulting in the solution being divided into a first phase which includes the polyoxoanion compound and the organic solvent, and a second phase. Step (2): Mix a hydrophobic organic solvent with the first phase to separate the solution into an organic phase which includes the organic solvent and the hydrophobic organic solvent, and a water phase which includes the polyoxoanion compound.
