The extraction of Fe 3+ from aqueous HCl solutions using tri-n-dodecylamine (TDA)/kerosene + 10% 2-octanol has been examined. The influence of HCl concentration, Fe 3+ concentration, organic to aqueous volume phase ratio (O/A), TDA concentration on the yield of Fe 3+ extraction have been investigated using 2 4 factorial design experiments. The effect of temperature on Fe 3+ extraction was found to be positive and the enthalpy change of the extraction reaction was found to be (∆H o = 45.609
