Description
Element 102, Nobelium (No), is an actinide with unique chemical properties. No exhibits +2 oxidation state in aqueous solutions and similar behavior to that of group 2 elements. However, recent studies have shown that No may be a softer acid. Further research is needed to understand No’s chemical properties, which might be influenced by relativistic effects. For a systematic chemical study of No, extraction with DGA ligands is proposed. In this work, we investigated the behavior of group 2 elements in extraction from nitric acid using DGA-resin and performed relativistic DFT calculations of extracted M(II)-DGA complexes.
