FIELD: chemical technology. SUBSTANCE: yttrium and rare-earth elements were separated by extractive mixture containing organophosphate compounds and hydrocarbon diluent. Organophosphate compound: phosphoric acid hexabutyltrisamide with additional addition of trialkylammonium nitrate and octyl alcohol at the following ratio of components, vol.%: phosphoric acid hexabutyltrisamide 38-42; trialkylammonium nitrate 8-12; octyl alcohol 8-12, and hydrocarbon diluent - the rest. EFFECT: improved method of elements separation. 2 tbl
