Abstract

A solvent extraction method is presented for the separation of95Nb from95Zr.95Nb is extracted quantitatively into a chloroform solution of α-benzoinoxime from 5N hydrochloric acid solution. By following the recommended procedure, a separation factor higher than 104 is achieved.95Nb can be back-extracted into concentrated hydrochloric acid. The radiochemical purity of the95Nb separated has been ascertained by half-life and γ-ray energy measurements. The whole procedure takes less than 20 min.
