FIELD: chemistry.
SUBSTANCE: invention relates to extraction of metals from water solution. Described are composition for extraction with solvent, which contains orthohydroxyaryloxime extractant, degradation-preventing agent and organic solvent which is not mixed with water. Also described is method of metal extraction from water solution with application of said composition. There exists method of reducing said composition degradation. Orthohydroxyaryloxime extractant is selected from: 5-(C8-C14 alkyl)-2-hydroxyacetophenonoximes, 5-(C8-C14 alkyl)-2-hydroxybenzaldoximes and their mixtures. Degradation-preventing agent represents element of the group, selected from: mono-, di- or tri-(1-phenylethyl)phenol, their mixtures and their isomers.
EFFECT: stabilisation of oximes, which are in contact with nitrate-containing raw material.
