研究了在有机稀释剂中磷酸三丁酯（TBP）萃取锆的行为。Zr在有机相中的分配比随TBP浓度的变化关系以及不同Zr和HNO 3浓度下Zr-TBP萃取物的红外光谱表明，30%TBP萃取时至少形成了两种可萃取的硝酸锆与TBP的溶剂化物。在HNO 3浓度不超过3 M时形成的溶剂化物含有水分子。在较高硝酸浓度下，水相中形成的可萃取物质是无水硝酸锆与TBP的溶解物。
The extraction of zirconium with tributyl phosphate (TBP) in organic diluent was studied. The dependence of the distribution ratio of Zr on the TBP concentration in the organic phase and also the IR spectra of Zr-TBP extracts obtained at different concentrations of Zr and HNO3in the aqueous phase show that at least two kinds of extractable zirconium nitrate solvates with TBP are formed in extraction with 30% TBP. The solvate formed at HNO3concentration not exceeding 3 M contains water molecules. The extract-able species formed at higher nitric acid concentration in the aqueous phase is anhydrous zirconium nitrate disolvate with TBP.
