Title:
SCANDIUM AND/OR LANTHANOID EXTRACTION METHOD
Document Type and Number:
Japanese Patent JP2016186108
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an efficient method of extracting scandium and lanthanoid usable in the mineral and industrial fields.SOLUTION: An acidic aqueous solution containing scandium and/or lanthanoid is brought into contact with an organic solvent in the presence of nitrilotriacetic acid triamide represented by the general formula (A) in the figure, so that the scandium and/or lanthanoid can be dissolved in the organic solvent and efficiently extracted. (In the formula (A), each R independently represents a C1-20 hydrocarbon group or hydrogen atom.)SELECTED DRAWING: Figure 1
