Title:
【発明の名称】水溶液中に存在するウラニウム(VI)及び/又はプルトニウム(IV)をN,N-ジアルキルアミドにより抽出する方法
Document Type and Number:
Japanese Patent JPH06104573
Kind Code:
B2
Abstract:
The invention relates to a process for the extraction of uranium (VI) and/or plutonium (IV) present in an aqueous solution by means of N,N-dialkylamides. These N,N-dialkylamides are in accordance with formula: (I) in which R1 is a straight or branched alkyl radical with 2 to 12 carbon atoms, R2 and R4, which can be the same or different, are straight or branched alkyl radicals with 2 to 6 carbon atoms, R3 and R5, which can be the same or different, are straight or branched alkyl radicals with 1 to 6 carbon atoms and a and b, which can be the same or different, are integers between 1 and 6. For example, it is possible to use N,N-di-(2-ethyl hexyl)-2,2-dimethyl butyramide, N,N-di-(2-ethyl hexyl)-hexanamide or N,N-di-(2-ethyl hexyl)-dodecanamide for simultaneously extracting uranium and plutonium, or for separating the uranium from the plutonium without reducing the latter.
