Description

The extraction equilibria of cerous, terbium and yttrium nitrates into Versatic Acid 911 were studied. The organic phase was diluted with benzene, and the ionic strength of the aqueous solutions was maintained at unity by adding NaNO3. Radioactive isotopes of these elements were used as the tracer. The compositions of the extracted species were CeR3.4RH.H2O, TbR3.4RH.H2O and YR3.4RH.H2o, and the apparent equilibrium constants of extraction were 9.14x10-15, 3.90x10-14 and 1.70x10-14, respectively.
