FIELD: chemistry.
SUBSTANCE: rhenium (VII) ions are extracted from aqueous solutions of protonated or neutral form of N',N'-di-2-ethylhexylhydrazide 2-ethylhexanoic acid. When extracting Re(VII) ions from aqueous solutions of the neutral form of N',N'-di-2-ethylhexylhydrazide 2-ethylhexanoic acid a modifier - 2 vol. % 2-ethylhexanol is used.
EFFECT: invention simplifies the process of extracting rhenium ions from acidic aqueous solutions.
