Title:
インジウム抽出剤およびこの抽出剤を用いたインジウム抽出方法
Document Type and Number:
Japanese Patent JP5420033
Kind Code:
B1
Abstract:
Provided are an extraction agent and extraction method that selectively extract and, at a low cost, recover indium from an acidic solution containing indium and zinc. The indium extraction agent comprises an amide derivative represented by general formula (I). In the formula, R1 and R2 each indicate the same or different alkyl group, R3 indicates a hydrogen atom or an alkyl group, and R4 indicates a hydrogen atom or any given group, other than an amino group, bound to the α-carbon as an amino acid. The general formula preferably has a glycine unit, a histidine unit, a lysine unit, an aspartic acid unit, or an N-methylglycine unit. By extracting indium from an acidic solution containing indium and zinc by means of solvent extraction using the extraction agent, it is possible to selectively extract indium.
