摘要：
The extraction of U(VI) from nitric acid solution with N,N,N′,N′-tetraoctyl diglycolamide (TODGA) has been investigated. The influence of diluents, nitric acid concentrations, TODGA concentration and salting-out agents on the extraction distribution ratio was studied. The extraction mechanism was established and the stoichiometry of the main extracted species was confirmed to be UO2(NO3)2·2TODGA. The extraction of UO22+ varies with the nature of diluents, sulfonated kerosene and dodecane gave high extraction distribution ratio.
