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 complexant des fluorures; on règle la solution aqueuse d'uranium obtenue à un pH d'environ 1 à 3, et on élimine les insolubles par filtration; on fait réagir avec un peroxyde, formant ainsi un précipité de peroxyde hydraté d'uranium-VI qu'on sépare. Le cas échéant, on peut soumettre à nouveau ce peroxyde à digestion en milieu aqueux acide en présence d'un agent complexant des fluorures, ajuster le pH de la solution à une valeur d'environ 1 à 3 et précipiter le peroxyde hydraté d'uranium-VI par addition d'un peroxyde. Applications courantes.
