SEPARATION OF PROTACTINIUM FROM CONTAMINANTS
Patent
·
OSTI ID:4236060
The separation of protactinium by volatilization method is described. According to the invention, neutron irradiated finely divided thorium is reacted with aluminum trichloride or a mixture of aluminum trichloride and chlorine gas at a temperature of preferably between about 200 and 400 deg C. Following the chlorinating step the protactinium chloride along with aluminum chloride is selectively distilled from the mixture at a temperature of approximately 100 deg C. The protactinium chloride may be recovered from the mixture by treatment with sodium hydroxide, which converts the aluminum chloride to a soluble salt and forms insoluble protactinium hydroxide.
