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