The present paper deals with the separation of zirconium and hafnium by means of paper chromatography.The system (tri-n-butyl phosphate,n-butanol and xylene or benzene) saturated with nitric acid of various concentrations (8-10N) was used as eluents.By verying the proportions of the components of the solvent system and nitric acid conceptrations,six eluents were prepared and tested.All of them gave satisfactory results and separated both elements completely.Under suitable conditions,a fairly large difference (about 0.5) in the RF-values between zirconium and hafnium can be attained.Hence,the eluents proposed may be used for the separation of these two elements.
