Title:
METHOD FOR PROCESSING FLUORINE-CONTAINING ELECTROLYTE SOLUTION
Document Type and Number:
WIPO Patent Application WO/2014/155784
Kind Code:
A1
Abstract:
A method for processing a fluorine-containing electrolyte solution, which is characterized by comprising: a vaporization step wherein the volatile component of an electrolyte solution that contains a fluorine compound is vaporized by heating the electrolyte solution at reduced pressure; a fluorine immobilization step wherein the fluorine component contained in the vaporized gas is reacted with calcium so as to be immobilized in the form of calcium fluoride; and an organic solvent component recovery step wherein the organic solvent component contained in the vaporized gas is recovered. Preferably, the volatile component of the electrolyte solution is vaporized by heating the electrolyte solution at reduced pressure after adding a small amount of water, an aqueous mineral acid solution or the like into the electrolyte solution.
