Abstract
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.
