Abstract

L'invention concerne un procédé de dissolution d'oxydes déposés sur un substrat métallique. Le but de l'invention est de décontaminer des substrats pollués par des dépôts de matières radioactives, sans attaque significative du substrat. Ce but est atteint à l'aide d'un procédé comprenant au moins un cycle consistant à: a) effectuer une attaque oxydante à l'aide d'une solution contenant au moins du permanganate, à une température comprise entre 80 et 85 °C, b) effectuer une attaque réductrice au moyen d'une solution comprenant un réducteur et de l'acide nitrique, à un pH inférieur à 2 et à une température comprise entre 80 et 85 °C.
