SOLVENT EXTRACTION OF INDIUM(3) WITH CARBOXYLIC ACIDS

The extractions of l0-5-10-7 M indium, from aqueous 0.1 M sodium perchlorate solutions into various organic media containing different concentrations of monocarboxylic acids and into pure monocarboxylic acids have been studied. Both saturated and unsaturated acids have been employed; the number of carbons in the acids was l-18. Detailed studies of one of the better systems, hexanoic acid in chloroform, have been carried out, the system has been described with a general overall equation, and identifications of the major species have been proposed. © 1968.
