By passing 0.2N hydrochloric acid solution of tnacer amounts of Zr/sup 95/ and Nb/sup 95/ (about 10/sup -11/ mole/1, 10/sup -13/ mole, or 1 mu c, with respect to each nuclide) through a cation exchange resin column (Dowex 50-X8, Amberlite IR120, or Diaion SK) and eluting with 0.2N hydrochloric acid, a fraction containing mainly Nb/sup 95/ was obtained. A fraction containing mainly Zr/sup 95/ was then obtained by eluting with 0.5% oxalic acid or 3N hydrochloric acid. With higher concentrations of nonactive zirconium and niobium (about 10/ sup -6/ mole/1 each), similar results were also obtained. As the 0.2N hydrochloric acid solution of Zr/sup 95/-Nb/sup 95/ became aged, the adsorbability of Zr/sup 95/ decreased. Effect of hydrochloric acid concentration on the adsorbability of Zr/sup 95/ and Nb/sup 95/ was studied, and the concentration range 0.1 to 0.3N was found to be suitable for separation. The adsorbability of Nb/sup 95/ increased with an increase in the concentration of strontium ion. (auth)
