Gallium extraction agent extraction of gallium and

The present invention provides a method from the group consisting of gallium, zinc in an acidic solution to selectively extract the gallium, and at a low cost method to extract and extracting agent recovered. The present invention provides a gallium extraction agent, which is an amide derivative represented by the following general formula (Ⅰ) indicated configuration. Formula, R1 and R2 each represent the same or different alkyl group, R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or a group as any α amino acid other than carbon-bonded amino group. Preferably glycine units having the following general formula, means histidine, lysine unit, aspartic acid unit, or N- methyl glycine units. By solvent extraction and extraction by the extracting agent containing gallium from gallium, and zinc acid solution, it is possible to selectively extract gallium.
