N2 - The extraction of iron(III) from aqueous solutions by di(2-ethylhexyl)phosphoric acid (DEHPA, HA) in hexane at constant ionic strength (0.5 M NaNO3), has been investigated under acidic conditions by means of metal distribution measurements. Iron(III) was extracted by ion-exchange reactions via the species: FeA3(HA)3, Fe2A3(HA)5 and Fe3A3(HA)3 in the organic phase. The corresponding stability constants were determined as: log β1 = 16.87, log β2 = 25.02 and log β3 = 18.39, respectively. © 1989.
