Title: STUDIES OF PROTACTINIUM IN AQUEOUS SOLUTIONS. IV. ION EXCHANGE METHOD
Abstract: The dependence of Pa/sup 233/ distribution on ion exchange resins on the concentration of HNO/sub 3/ (1 to 14n) indicates that protactinium appears as a complex ion of variable charge. The mean cation charge is 3, which corresponds to a maximum in HNO/sub 3/ (1 to 4n) solution. In > 5n nitric acid, protactinium forms various negatively charged complexes. The mean charge of Pa anions on resins (8 to 12n HNO/sub 3/) is 3. The probable maximum anion charge in HNO/sub 3/ solution is 3. (R.V.J.)
