摘要：
The extraction of Th(IV) and UO22+ by a solution of TTA and HDEHP, respectively in toluene has been used to obtain stability constants of their oxalate complexes at 298 K in 1, 3, 5, 7 and 9M ionic strength (NaClO4) solutions. The complexes formed were the MOx, MHOx, MOx(2) and M(HOx)(2) (M = Th, UO2) species. The values were analyzed by the Specific Interaction Theory and agreed to I less than or equal to 3 M but required an additional term for fitting at I > 3 M.
