Aqueous Speciation and Solvent Extraction of Antimony in Nitric and Hydrochloric Acids Relevant to Nuclear Fuel Reprocessing

This dataset contains the solvent extraction and XAFS data underlying the study on aqueous speciation and solvent extraction behavior of antimony (Sb) in nitric acid and hydrochloric acid media. The dataset includes distribution ratios obtained with TBP, TDdDGA, and TEHDGA under varying HNO₃, NO₃⁻, extractant, and HCl conditions, together with XAFS data used to evaluate the oxidation-state distribution of dissolved Sb in nitric acid solutions.
