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,效果尚好。二者R_F值之差仅为0.1。据称比之用乙醚-硝酸作展开剂为好。磷酸三丁酯曾用于锆铪之萃取分离,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R_F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。 Kember and other use of trichloroethane - concentrated nitric acid (3: 7) as a developing agent for zirconium hafnium paper color separation, the effect is good. The difference between the two R_F values ​​is only 0.1. It is said to be better than ether-nitric acid. Tributyl phosphate has been used for the extraction and separation of zirconium and hafnium, so this paper studies the color separation of zirconium and hafnium paper by using nitric acid tributyl phosphate-n-butanol-xylene as developing solvent. The result is very good, the difference between the two R_F values, under good conditions up to about 0.5. However, the resulting spots are still not focused enough.
