This study aimed to study the parameters, which affect the separation of gadolinium(III) fromsamarium(III) and determine extraction efficiency (%E) and stripping efficiency (%S). Parameterselection was made to design experiment using two-level factorial based on response concentration ofgadolinium(III) maximum and samarium(III) minimum. A simulation sample of a mixture ofgadolinium(III) and samarium(III) was mixed with an emulsion prepared from a mixture ofdi-2-ethylhexyl phosphoric acid (D2EHPA) or tributylphosphate (TBP) ligands extractant, surfactantand the internal phase. Then the extraction and stripping results were analyzed using ICP-AES. Theresults for %E and %S separation of gadolinium(III) from samarium(III) were 72.48% and 48.46%,respectively.
