Abstract
Procédé de préparation de résines de polybromure stabilisées utilisables pour désinfecter l'eau, dans lequel des perles poreuses de résine échangeuse d'anions d'ammonium quaternaire, contenant de l'eau sont chargées de brome, ce procédé comprenant notamment le chargement de ces perles de résine dans une pate aqueuse contenant du brome, ce chargement conférant aux perles un excès de brome au-dessus de la teneur en brome désirée dans le produit final, la séparation de l'eau extérieure des perles chargées et le passage d'air évaporant l'humidité à travers une masse de ces perles humides à une température et une vitesse controlées.
