| Abstract: | The extraction of Fe(III) from a nitrate medium of ionic strength 1.0 mol dm?3 by n-dodecanoic acid (HA) dissolved in toluene has been studied by distribution measurements. Experimental data, treated by different graphical and numerical methods, have been explained assuming the extraction of the species (FeA3)3 into the organic phase as well as the formation of a Fe(III)-HA complex in the aqueous phase. |
