As a result, it is determined that the thorium(IV) complexes are considerably more stable than the corresponding uranium(VI) complexes. on the other hand, the complexes formed between 8-HOQ-5-SO3H and uranium(VI) or thorium(IV) are less stable than the corresponding 8-HOQ complexes.en10.1007/BF02162616info:eu-repo/semantics/closedAccessArticle1864325332WOS:A1994NE18000004N/A
