Title:
ELECTROLYTIC REDUCTION RECOVERY METHOD OF METAL ION IN ORGANIC SOLVENT
Document Type and Number:
Japanese Patent JP2020152931
Kind Code:
A
Abstract:
To develop a method of recovering a metal ion in an organic phase as a higher purity metal by simplifying an operation by removing a solution for a back extraction which is utilized by separating and recovering only a target metal from an acidic solution.SOLUTION: As an example, after extracting vanadium in an organic solvent (acetophenone, dichloroethane, octanol) by using MIDOA as an extraction agent, a support electrolyte is dissolved, followed by electrolyzing under an over-voltage of -2.5 V to precipitate as a metal on a surface of an electrode for recovery.SELECTED DRAWING: Figure 1
