Description

The extraction of protactinium(V) from strongly acidic solutions of mineral acids is carried out with benzene solution of thenoyltrifluoroacetone. To interpret the data obtained, two extraction mechanisms representing the descending and ascending parts of the extraction curves are suggested. At lower acidity the formation of PaO(TTA)3.HTTA species predominates. At higher acidity an ion-pair formation between anionic protactinium inorganic complex species and H2TTA+ cation is assumed.
