Abstract The extraction separation of La and Sm by benzyldibutylamine (BDBA) from an aqueous solution containing 6 mol·dm−3 NaNO3 and 0.5 mol·dm−3 HNO3 is not very efficient. It may remarkably be improved by addition of a complexing agent, 2-hydroxyethylethylenediaminetriacetic acid (HEDTA). The effect of preferential La extraction into the organic phase together with the effect of preferential complexation of Sm in the aqueous phase may lead, by proper choice of the complexing agent concentration, to a 7–10 fold increase in αLa/Sm values. The procedure described here enables fairly good separation of a major from minor elements.
