Ferrous chloride, Interaction parameter, Solvent extraction, Amine
Distribution diagram of FeCl2 in HCl solution indicated that FeCl+ was a predominant species in strong HCl solution up to 10 M. Solvent extraction of FeCl2 has been performed in the HCl concentration range from 5 to 9 M by using Alamine336 as an extractant. Interaction parameter of FeCl+ for Bromley equation was estimated from our solvent extraction data. This parameter thus obtained in our study can be employed in calculating the activity coefficient of FeCl+ in high concentration of HCl.
