FIELD: metallurgy.
SUBSTANCE: method of extracting rhenium from uranium-containing solutions involves the sorption of rhenium by a weakly basic nanostructured ion exchanger on a styrene acrylate matrix containing cyclohexylamine functional groups in an amount of 1.9-3.0 meq/g.
EFFECT: increasing selectivity of rhenium extraction with respect to uranium, reducing sorption-desorption stages during purification of eluted rhenium solutions from uranium, improving sorption-desorption characteristics of technical and economic parameters of sorption extraction of rhenium from uranium-containing solutions.
