Abstract

Préparation de peroxyde hydraté d'uranium-VI purifié à partir de tétrafluorure hydraté d'uranium. On fait digérer le tétrafluorure en solution aqueuse acide en présence d'un agent de précipitation des fluorures; on filtre les insolubles et les fluorures précipités; on règle la solution aqueuse d'uranium obtenue à un pH d'environ 1 à 3; on fait réagir la solution avec un peroxyde pour précipiter l'uranium-VI sous forme de peroxyde qu'on sépare. Applications courantes.
