Title:
The extraction separation method of a rare metal using Nitorirolotri aceto amide
Document Type and Number:
Japanese Patent JP6083862
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for extraction separation enabling many kinds of rare metals to be recovered at a time.SOLUTION: There is provided a method for extraction separation of rare metals from a hydrochloric acid solution or a nitric acid solution by using as an extractant, nitriloacetamide represented by the general formula, where R is an alkyl group having 6 to 12 carbon atoms. The rare metal is preferably one or more kind selected from among Nb, Ta, Cr, Mo, W, Re, Ru, Ir, Pd, Pt, Ga, In, Sb, Bi, Te, Hg, Tc and V. The rare metal is solvent-extracted from the hydrochloric acid solution or the nitric acid solution by using an extraction solvent obtained by solving nitriloacetamide in an organic solvent, or the rare metal is extraction-separated from the hydrochloric acid solution or the nitric acid solution by passing the hydrochloric acid solution or the nitric acid solution containing the rare metal through a solid adsorbent obtained by impregnating nitriloacetamide into a resin.
