Solvent extraction of Ga(III) and In(III) from aqueous halide media by adogen-364

Adogen-364 has been used for the extraction ofgallium(III) and indium(III) from halogen acid solutions, and the dependence of the extraction on chloride, bromide and iodide ion concentration studied. The separation of Ga(III), In(III) and Al(III) is reported and some conclusions have been drawn about the stoichiometry of the extracted species.
