Abstract
The extraction of Fe(III) and Fe(II) from various aqueous acidic solutions, with nitrobenzene, Amberlite LA-2, TBP and HDEHP is described. Conditions are given for the separation of Fe(III) from Fe(II). The extraction and separation of Fe(III) and Fe(II) is most adequate from HCl solutions, using the four solvents. The extraction of iron halides from H2SO4 solutions has been studied. The effect of water-miscible alcohols on the distribution of Fe(III) and Fe(II) was also studied. Extraction equilibria and mechanisms were proposed on the basis of the obtained results.
