Abstract  

Data are presented on the distribution of trace amounts of tantalum (V) between different mineral acid solutions and 0.1M solutions of N-oxides of 4-(5-nonyl)pyridine and trioctylamine. The optimal acidity is 0.01–0.5M, depending on the nature of the acid. Common anions have little effect on extraction. Possible mechanisms of extraction are suggested making use of slope analysis data. Separation factors for a number of metal ions with respect to tantalum are reported for the 0.1M 4-(5-nonyl)pyridine oxide—1M sulphuric acid extraction system. Separation from uranium(VI), thorium(IV) and a number of fission products is suggested.
