Abstract
In this paper, experiments on the extraction of 233Pa into tri-n-butyl phosphate from hydrochloric acid solutions are described. The effect of fluoride, phosphate, citric, lactic and tartaric acids on the distribution coefficient was studied. Ethyl acetoacetate was found to be a good extracting agent. A semi-closed type apparatus has been designed for use in electro-phoresis studies of 233Pa in HCl solutions. From the variation of the anion/cation ratio with the concentration of HCl the nature of the cation to anion conversions could be inferred. The mobility of 233Pa is greatly enhanced by the presence of traces of fluoride ion, and the histograms clearly indicate the presence of cationic species.
