Abstract

The separation of metals from uranium by anionic exchange was studied. The behaviour of ions in Dowex 1x8 in HNO3, H2SO4, HC1, HCL-HF, and NH3 media, and Dowex 2x8 in H2SO4 medium were investigated. Methods for the separation of Na, Mg, Al, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Zr, Ag, Cd, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Yb, La, Hf and Th were developed. For Mo, partial separation was obtained. Separation schemes for the neutron activation analysis of metallic impurities in uranium are proposed. The detection limits are given. The results for the elements Al, Cr, Mn, Co, Ni, Cu, V and Fe determined from the IAEA reference samples SR-54/64 are compared with recommended values.
