Kember等用二氯三缩乙二醇-浓硝酸(3:7)为展开剂作锆铪的纸上色层分离[1],效果尚好。二者RF值之差仅为0.1。据称比之用乙醚-硝酸作展开剂[2]为好。磷酸三丁酯曾用于锆铪之萃取分离[3,4],故本文以含硝酸的磷酸三丁酯-正丁醇-二甲苯为展开剂研究锆与铪的纸上色层分离。所得结果甚好,两者RF值之差,在良好的条件下可达0.5左右。但所得之斑点仍嫌其不够集中。

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.
