DETERMINATION OF DISTRIBUTION FACTORS OF URANIUM AND FISSION PRODUCT ELEMENTS IN HCl-ANION EXCHANGER SYSTEM

    Graphical Abstract
    • Abstract
  • In this work the distribution factors K_d s of uranium and fission product ele-ments (Zr, Nb, Mo, Pd, Ag, Cd, Sb, Te, U etc.) in 0-12 mol/1 HCl or HCl plusa little HNO_3-Anion exchanger (20×7) system are determined by a static equili-brium method. The K_ds of Zr, Nb and Sb (V) increase with decreasing acidity. When theacidity of the medium is near neutral, there is a minimum K_d of Mo at 0.5--1mol/1. In addition, the existence of a little HNO_3 (0.3--0.5 mol/1) does not effectthe K_d s very much, except that the K_d of Pd (Ⅱ) increases by about one order of magnitude.
