Thermodynamic of lanthanum (iii) and samarium (iii) extraction by using stoichiometric concentration solutions of naphtenic acid

Article preview

Experimental data on solvent extraction of lanthanum (III) and samarium (III) by solutions of naphthenic acid from nitrate medium was obtained. Dependences of distribution coefficient of pH, concentration of organic and aqueous phase was obtained. thermodynamic characteristics of extraction equilibrium was calculated.
