The Nitrate Dependence of the Dysprosium Distribution Coefficient at Constant Ionic Strength in the Synergistic System Kerosene/HTTA/TBP/Dilute HNO 3

Abstract
Analysis of dysprosium distribution data determined at varying nitrate concentration but constant ionic strength indicates that the dysprosium exists in the aqueous phase as Dy (NO3)+1 2. The corresponding complex which is extracted into the organic phase is taken to be Dy(NO3)(TTA)2(TBP)2.
