Zusammenfassung:	FIELD: chemistry.SUBSTANCE: method of extracting copper (II) ions from ammonia solutions using an extractant consisting of a mixture of 1-phenyl-3-heptyl-1,3-propanediol and 2-ethylhexanoic acid in amount of 5-10 mol % of the content of 1-phenyl-3-heptyl-1,3-propanediol in an organic solvent which is immiscible with water.EFFECT: invention shortens the copper ion re-extraction time.3 tbl, 2 ex Изобретение может быть использовано в области гидрометаллургии цветных металлов и в химической промышленности. Способ экстракции ионов меди (II) из аммиачных растворов с использованием экстрагента, состоящего из смеси 1-фенил-3-гептил-1,3-пропандиона и 2-этилгексановой кислоты в количестве от 5 до 10 моль % от содержания 1-фенил-3-гептил-1,3-пропандиона в органическом растворителе, несмешивающемся с водой. Изобретение позволяет снизить время реэкстракции ионов меди (II). 3 табл., 2 пр.
