Beschreibung
Zusammenfassung:	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+ + 3C12H25OSO3Çè- = 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. ^ 3 dwg, 1 tbl Изобретение может быть использовано в химической промышленности. Ионы самария и европия извлекают ионной флотацией с додецилсульфатом натрия, взятом в соотношении 1:3 по стехиометрической схеме Me3++3C12H25OSO3 -=Ме(C12H25OSO3)3, где Me - катион самария или европия, C12H25OSO3 - додецилсульфат-ион. Изобретение позволяет достигать 99,9%-ного извлечения ионов самария и европия. 2 ил., 1 табл.
