VON URAN(VI) UNTER VERWENDUNG EINER WÄSSRIGEN SALPETERSÄUREPHASE IN EINEM URANEXTRAKTIONSZYKLUS |
摘要 |
<p>A chemical element to be very efficiently separated from uranium starting from an acid aqueous phase, in an extraction cycle for the uranium, when this chemical element is present in said phase at a concentration less than that of the uranium, or even as a trace element, and when it is moreover less extractable by the extractant used in this extraction cycle than is the uranium. The chemical element can notably be neptunium(IV) or thorium 228.</p> |
