ION EXCHANGE IN SOLVENT MIXTURES. III. ON THE DISTRIBUTION OF THORIUM CHLORIDES BETWEEN THEIR ALCOHOLIC HYDROCHLORIC ACID SOLUTIONS AND STRONGLY BASIC ANION EXCHANGERS (in German)
The existence of negatively charged chloride complexes of thorium was investigated. Since it is a well-known fact that in aqueous solutioms containing hydrochloric acid no such complexes are formed, different alcohols of the aliphatic series were substituted for water. Through the measurements of the distribution coefficients at different acidities of hydrochloric acid and at varying concentrations of alcohols, it is concluded that the adsorption of thorium on strongly basic anion exchangers is very high if the alcohol is present in a very high percentage. At the same time the amount of hydrochloric acid present (i.e., the over-all acidity of the solution) resulted in no effect on the adsorption of thorium on these exchangers. By means column operations, the batch experiments, which led to the determination of the distribution coefficients and an adsorption isotherm, were verified. (auth)
