FIELD: metallurgy.
SUBSTANCE: extraction method of rare-earth elements from solutions containing multiple excess iron (III) and aluminium, with pH=0.5÷2.5 involves sorption using macroporous sulfocationite as sorbent. At that, as sorbent there used is macroporous sulfocationite containing more than 12 to 20% of divinyl benzene.
EFFECT: effective extraction of amount of rare-earth elements from solutions.
