Single-stage batch experiments to extract fission products (FPs) and trivalent minor actinides (MA(III)) were performed by setting the concentrations of TBP, nitric acid, and NO₃^- as parameters, and the distribution ratios of these elements were evaluated. We report the effects of the concentrations of NO₃^- and free TBP on the extraction behavior of FPs and MA(III).
