FIELD: medicine, pharmaceutics.
SUBSTANCE: invention can be applied in chemical industry, metallurgy and purification of industrial and domestic sewages. Extraction of iron with vegetable oils is realised from water solution with ratio water (W) to organic (O) phase W:O≥3 for Fe (III) and W:O= 3-6 for Fe(II); at pH 2-3 for Fe (III) and 9-11 for Fe (II) and Fe (III). Time of extraction for Fe (III) is 1-3 min and not more than 60 min for Fe (II).
EFFECT: method ensures high degree of efficiency of iron extraction from water solutions with simultaneous efficiency and safety of the process.
