Abstract

Procédé pour séparer le radium d'une solution aqueuse d'acide inorganique, suivant lequel on met la solution en contact avec des cendres volantes pour faire adsorber le radium par les cendres. Les cendres chargées de radium sont ensuite séparées de la solution. Le procédé est simple, relativement peu onéreux et efficace. Le coefficient de distribution du radium atteint des valeurs élevées, meme à la température ambiante. Le procédé permet de traiter les rejets des usines d'uranium.
