The possibilities of 90Y/90Sr separation from carbonate media are investigated as a green alternative method. Solvent extraction of yttrium and strontium from carbonate solution is studied using several extractants in different organic diluents. 8-hydroxyquinioline and 2,3-dihydroxynaphtalene possess a promising Y/Sr separation. Yttrium and strontium distribution ratios D and separation factors SF are evaluated. pH interval 13 - 13.5 is regarded as the optimum for separation. Yttrium is extracted much better in 2-nitrotoluene (DY=3.9), maximum separation is observed in 2-nitrotoluene SF = 195 at pH 13.5.
