摘要： The present invention relates to a process for the selective separation of actinides (III) and lanthanides (III) from a reaction medium containing them. More specifically, the invention permits a selective extraction of actinides (III) by using an aqueous reaction medium containing TcO.sub.4.sup.- pertechnetate ions. The preferred extracting agents are chosen from among picolinamides and their derivatives. A particular use of the process is in the separation of actinides (III) from high activity raffinates produced during the reprocessing of nuclear fuels according to the solvent-based extraction process known as the PUREX process.

摘要： The invention relates to the elimination of the chloride ions present in contaminated solid wastes, such as incineration ashes contaminated by actinides.First the chloride ions are dissolved in an aqueous solution, for example a nitric acid solution of 4 to 6 moles/l, whereafter the chloride ions thus dissolved in the aqueous solution are oxidized, for example, electrochemically, possibly in the presence of an oxidation-reduction couple such as CO.sup.3+ /CO.sup.2+, to eliminate them from the solution in the form of chlorine in a gas flow.The dissolution and oxidation can be performed in the electrolyzer (1), the gas flow being introduced at (10) and eliminated at (13). Then the actinides can be dissolved directly in the electrolyzer by electrolysis in the presence of Ag.sup.2+ ions.
