- 論文の詳細を見る
The behavior of pentavalent protactinium in sulfuric acid solutions was investigated by paper electrophoresis and by the TTA-benzene extraction method. From the results of this investigation, it is recognized that the Pa(OH)_2(SO_4)^+ ion exists predominantly in dilute sulfuric acid solutions (pH 0.4-2.2), and that the complexing reaction of pentavalent protactinium by the sulfate ion may proceed as ; chemical formula. The stability constant of Pa(OH)_2(SO_4)^+ was also determined by the solvent extraction method to be 6.4 at an ionic strength of 1.38.
