Abstract

The distribution ratios, Kd, for zirconium and hafnium were measured in the hydrochloric acid-TBP-celite system, the acid concentration being varied from 5 N to 8 N. The data obtained showed that the separation factor for the above elements, KdzrKdHf, is fairly high, –4, in the 7–8 N hydrochloric acid range. Thus, the separation of these elements was carried out in 7.1 N hydrochloric acid by the use of a TBP-celite column.
