FIELD: chemistry.
SUBSTANCE: method of extracting yttrium (III) from salt solutions involves floatation extraction using an organic phase and a collector. The organic phase used is isooctyl alcohol. The collector used is an anionic surfactant - sodiium dodecyl suphate in a concentration which corresponds to the stoichiometry: Y+3+SDS-=Y[DS]3, where Y+3 is a yttrium cation, DS- is a dodecyl sulphate ion. Floatation extraction is carried out at pH=7.0-7.8 and ratio of the organic phase to the aqueous phase of 1/20-1/40.
EFFECT: high degree of extraction of yttrium.
