Özet

Solvent extraction reaction of Mn(II) by Alamine336 from strong HCI solution up to 10 kmol/m3 was identified from the experimental data by using slope analysis method. The equilibrium constant for this solvent extraction reaction was estimated by considering the complex formation reactions between Mn(II) and chloride ion. The activity coefficients of solutes present in the aqueous phase were calculated by Bromlev eauation. The necessary thermodynamic parameters for the formation of MnCl+ were evaluated from the data reported in the literature. The measured distribution coefficients of Mn(II) agreed well with those calculated in this study. © 2008 The Japan Institute of Metals.
