Work was carried out in order to develop a method for separating thorium and uranium. Equilibrnnum studies show that the adsorption of both tetravalent thorium and hexavalent uranium as negatively charged chloride complexes on the strongly basic anion exchanger Dowex l from solutions containing butanol and hydrochloride acid is very high, so that these two radio elements can be adsorbed on tbe resin simultaneously. Separation is possible due to the fact that thorium can be readily eluted with a methanol-hydrochloric acid mixture, whereas uranium is still very strongly retained on the resin under the same conditions. After the removal of thorium the uranium is eluted with I N hydrochloric acid. (auth)
