Description
The object of the invention is a method for separating the isotopes of an element in the ion state. To that end, the element, the isotopes of which are to be separated, is used in the form of an ionized salt dissolved in a polar gas, e.g. steam, taken above its critical point. Ions move much more easily in gases than in liquids and, through a gaseous-phase counter-current electrolysis, a fast separation of the isotopes is obtained. The invention can be used for generating enriched uranium widely used in modern electric power-stations, as well as for preparing isotopes for the pharmaceutical industry or analysis laboratories
Abstract (French)
L'invention a pour objet un procede permettant de separer les isotopes d'un element pris a l'etat d'ions. A cet effet l'element dont on veut separer les isotopes est utilise sous forme de sel ionise dissous dans un gaz polaire, comme la vapeur d'eau, pris au-dessus du point critique. Les ions sont bien plus mobiles dans le gaz que dans un liquide et par electrolyse en contre-courant en phase gazeuse, on arrive a une separation rapide des isotopes. L'invention peut etre utilisee pour preparer l'uranium enrichi, tres employe dans les centrales electriques modernes, ainsi que pour la preparation des isotopes destines a l'industrie pharmaceutique ou aux laboratoires d'analyseAdditional details
