Extraction of uranium (VI) and thorium from hydrochloric acid solutions by tri-n-butyl phosphate

The partitions of uranium (vi) and thorium between hydrochloric acid solutions and solutions of tri-n-butyl phosphate (TBP) in benzene or kerosene have been investigated at different concentrations of hydrochloric acid and solvent, and at different temperatures. An infra-red spectral study has also been made of the organic solutions obtained in the extraction of uranium. The effect of organic solvent on the extractions has also been examined.
