The study of thermodynamics plays an essential role in the analysis of the ion exchange process. In the present study extraction of yttrium(III) from aqueous solution was investigated using Dowex 50W X8 resin. The amount of gibbs free energy changes (ΔGo) was always positive and the amount of entalphy changes (ΔHo) was equal to 12.42 kJ/mol, which showed that the process of ion exchange of yttrium(III) from acidic aqueous solution is non-spontaneous and endotermic reaction.
