摘要：
The extraction characteristics of nitric acid with a typical TRUEX (transuranic elements extraction) solvent, the mixture of octyl(phenyl)-N, N-diisobutylcarbamoylmethylphosphine oxide and tri-n-butyl phosphate dissolved in n -dodecane, were studied. From the extraction results of lanthanum, the concentration of CMPO, which was not bound to metal ions or nitric acid, were estimated. The estimated concentration was appropriate in comparison with the extraction results of nitric acid. The applicability of the determined effective CMPO concentration to the formulation of the distribution equilibrium of other f-elements was confirmed.
