The complexes formed were the MOx, MHOx, MOx2 and M(HOx)2 (M = Th, U02) species. The values were analyzed by the Specific Interaction Theory and agreed to / < 3 Μ but required an additional term for fitting at / > 3 M.EnglishThoriumUranylOxalateComplexationSolvent extractionArticle10.1524/ract.1994.6667.special-issue.1232193-3405
