FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Samarium and europium ions are extracted through ionic floatation with sodium dodecylsulphate, taken in ratio of 1:3 according to the stoichiometric equation Me3+ + 3C12H25OSO3 - = Me(C12H25OSO3)3, where Me is a samarium or europium cation, C12H25OSO3 is the dodecylsulphate ion.
EFFECT: invention enables to achieve 99,9% extraction of samarium and europium ions.
