Abstract
Extraction properties of 4d element (Ti, Zr, and Hf) salts of dibutylphosphoric acid (HDBP) are examined. In extraction of Eu from nitric acid solutions, the optimal [HDBP]/[M] ratio depends on the presence of TBP and a diluent in the extraction system and also on the HNO3 concentration in solutions. With decane used as a diluent instead of xylene, the distribution coefficients of the extracted elements increase, and the extracting properties of the Zr and Hf salts become more similar. The extraction characteristics of these salts are similar over the entire examined range of HNO3 concentrations. At the same time, the difference between the Zr and Hf salts in the extractive power applies to all the lanthanides. The extraction properties of the Ti salt strongly differ from those of the Zr and Hf salts. Thorough study of the behavior of the Ti salt is complicated by its limited solubility in organic solvents.
