Abstract
Abstract The use of LIX 973N for extraction of indium (III) from sulphate media is studied. The extraction system is studied as a function of equilibration time, temperature, diluent and metal and extractant concentrations. Experimental data have been analyzed graphically and numerically to determine the stoichiometry of extracted species and their equilibrium constants. It was found that indium was extracted into the organic phase by formation of the InR 3 species (log K ext =−7.7 (graph.), log K ext =−8.27±0.04 (num.)). The effect of aqueous ionic strength on indium extraction was also studied.
