    • Abstract
  • The effect of HNO 3 concentration on distribution ratio of Tc between 30 % TBP Kerosene and HNO 3 solution at various ratio of U, Zr, Tc is studied. The extraction behavior and trend of Tc in 1A extractor are obtained with mixer settler. Results show that 14.4 % and 27.0 % of Tc is in 1AP while concentration of HNO 3 in 1AF solution are 2 mol/L and 3 mol/L, respectively. However after heating pretreatment of 1AF solution, 99.8 % of Tc is in 1AP while concentration of HNO 3 in 1AF is 3 mol/L.
