Selectivity of Amidoxime Polymers for the Sorption of Gallate
The sorption of gallium from alkaline solution using amidoxime resins or polyampholytes was studied. Gallium is extracted by amidoxime resins, even from Bayer leachates, but amidoxime polyampholytes are limited to dilute alkali hy droxide solution up to 5 M. The elution of gallium runs well with acetylacetone.
