Abstract:The extraction of uranyl nitrate by novel extractants of N,N-dimethyl-N＇,N＇ -dioctylsuccinylamide (DMDOSA) and N,N-dimethyl-N＇,N＇ -didecylsuccinylamide (DMDDSA) from aqueous nitric/nitrate solutionswasinvestigated. It was found both the concentration of HNO3 and extractants had an effect on the U(VI) extraction distribution. The extraction mechanism was established, and stoichiometry of the main extracted species was confifirmed to be UO2(NO3)2 2DMDOSA and UO2(NO3)2▪ 2DMDDSA, respectively. Both of the extraction reactions are exothermic……
