Column chromatographic separation of gallium, indium and thallium.
Distribution ratios are given for the extraction of gallium-(III), indium(III) and thallium(III) from aqueous solutions of hydrobromic acid into di-isopropy ether and isobutyl methyl ketone. Based on the results obtained, a scheme is presented for the quantitative separation of these elements from each other by liquid-liquid partition chromatography. The effect of a number of other metal ions upon the separation is also studied. The separation method has been applied to the analysis of a series of lead-indium alloys.
