METHOD FOR SEPARATING ACTINOID ELEMENT

摘要

PROBLEM TO BE SOLVED: To make it possible to separate actinoid elements from each other with high efficiency by a unit manipulation technique at room temperature and under normal pressure which needs no oxidization manipulation so that less secondary waste is generated and is not attended with an engineeringly difficult precipitation manipulation.

SOLUTION: A solution containing actinoid elements such as americium, curium and californium is supplied to a resin column filled with a weak basic anion exchange resin of the first, second and third classes formed by making pyridine, imidazole alkylamine and the like resin and an eluted solution made by mixing nitric acid with alkyl alcohol such as methanol, ethanol and propanol is used to separate the actinoid elements from each other by chromatography.
