Abstract

Une nouvelle methode de preparation de sources minces radioactives est basee sur deux etapes: - (1) la preparation de films minces et - (2) l'incorporation d'elements radioactifs par un procede de chelation. Nous presentons quelques proprietes du monomere N-hexyl-pyrrole 2N,N'dimethyl dibutyl malonamide. Les films minces sont obtenus par electropolymerisation de ce monomere dans l'acetonitrile. Cette methode permet la synthese de polymeres d'epaisseur controlee contenant des ligands chelatants. Le coefficient de distribution limite et le rendement de fixation ont ete determines pour l'uranium(VI) dans un milieu nitrique de trempage.
