AbstractAbstract
[en] Extraction mixture for U(6) isolation from phosphoric acid solutions, containing 80-84 mol.% of di-2-ethylhexylphosphoric acid and 16-20 mol.% of di-n-hexylocthydroxymethyl phosphine oxide is suggested. Example of the use of the mixture suggested for uranium extraction from H3PO4 6M solution, containing 1 g/l uranium and 1 g/l iron, is given. The coefficient of uranium distribution in the case constitutes 6.74, uranium and iron separation coefficient is 112. The extraction mixture is recommended for the use in uranium processing
