Rhenium(VII) solvent extraction with synergistic mixtures of neutral extractants (octyl alcohols and ketones) from sulphuric acid media has been investigated. It was observed that the synergistic effect appeared under solvent extraction from high acid solutions, consisting ≥ 5 mol/L H2SO4.The synergistic coefficients were up to 2–2,3 providing 97,5–98,7% rhenium(VII) extraction efficiency at one SX step. High rhenium(VII) SX efficiency maintained in the wide range of extraction mixtures compositions (10–50 % v/v of ketone).
