| Abstract: | Equilibrium distribution ratios have been determined for uranium(VI) with oxine between chloroform and 0.1M perchlorate as a function of pH and reagent concentration at 20 degrees . It is concluded that the extractable complex is UO(2)Ox(2)HOx. The equilibrium constants for the extraction of uranium have been determined as K(u,1) = UO(2)Ox(2)HOx](0)/UO(2)(2+)]Ox(-)](3)H(+)] = 10(36.18) at low pH and K(U,2) = UO(2)Ox(2)HOx](0)/UO(2)Ox(2)OH(-)]Ox(-)]H(+)](2) = 10(25.40) at high pH. |
