Method for removing inorganic matter from solid surfaces

   
   

Metal ions are removed from solid surfaces which may be contaminated with one or more radionuclides by contacting the solid surfaces with the supercritical fluid, as, for instance, carbon dioxide containing both an acidic ligand and organic amine. The metal ions are extracted from the solid surface and the extract is separated from the solid surface.

Los iones del metal se quitan de las superficies sólidas que se pueden contaminar con unos o más radionuclides entrando en contacto con las superficies sólidas con el líquido, el as, por ejemplo, el bióxido de carbono supercríticos que contiene un ligand ácido y la amina orgánica. Los iones del metal se extraen de la superficie sólida y el extracto se separa de la superficie sólida.
