FIELD: chemistry.
SUBSTANCE: method of extracting cerium cations from aqueous solutions of its salts involves use of a sodium dodecyl sulphate surfactant collector with concentration corresponding to the reaction stoichiometry: Ce+3+3DS-=Ce[DS-]3, where Ce+3 is a cerium cation, DS- is a dodecyl sulphate ion. Cerium cations are extracted via flotoextraction in an organic phase at pH=7.6-8.3. The organic phase used is isooctyl alcohol.
EFFECT: high degree of cerium extraction.
