抄録

In order to see the separation efficiency of the high temperature electrorefining of thorium, mixtures of thorium and other metals were electrorefined in a fused salt bath containing sodium and potassium chlorides. In these experiment, radioactive tracers were used to estimate the micro-quantities of these elements. Cobalt and lead, which have lower reversible decomposition voltage, can be thoroughly eliminated as anode slime. And the contents of these elements in the cathode deposites were about 10−10%. Titanium, zirconium and uranium, which have only a few tenth volt of difference, were also separated fairly well. Rare earth elements, which have high absorption cross section for thermal neutron, can also be removed in this process, because the electrode potentials of these elements are rather high. Activation analysis by neutron irradiation showed that the refined thorium contained less than 5 ppm of Dy and Sm.
