| titleOfInvention | Process for recovering molybdenum-99 from a target of an irradiated uranium alloy |
| abstract | a) - dissoudre la cible d'alliage d'uranium irradié dans de l'acide sulfurique, b) - séparer l'iode et le tellure présents dans la solution ainsi obtenue, c) - oxyder le molybdène-99 présent dans la solution en Mo(VI), et d) - extraire le molybdène-99 ainsi oxydé par un acide hydroxamique de formule :n dans laquelle R est un radical choisi dans le groupe comprenant les radicaux alkyle linéaires ou ramifiés, le radical phéhyle, les radicaux phényle substitués par au moins un radical alkyle, les radicaux aryl-alkyle et le radical cyclohexyle, et R' est un atome d'hydrogène ou un radical alkyle.The invention relates to a process for recovering molybdenum-99 from a target of irradiated uranium alloy. This process includes the following successive steps a) - dissolve the target of irradiated uranium alloy in sulfuric acid, b) - separating the iodine and the tellurium present in the solution thus obtained, c) - oxidize the molybdenum-99 present in the solution to Mo (VI), and d) - extract the molybdenum-99 thus oxidized with a hydroxamic acid of formula: in which R is a radical chosen from the group comprising linear or branched alkyl radicals, the phenyl radical, the phenyl radicals substituted by at least one alkyl radical, the aryl-alkyl radicals and the cyclohexyl radical, and R 'is an atom d hydrogen or an alkyl radical.n n n The hydroxamic acid can be tri n-butytecétohydroxamic acid, the molybdenum recovered can be used in a technetium generator for medical uses. |
