Extraction Species of Niobium and Tantalum with Some Novel Extracting Agents

  • C. Djordjević

Abstract

Niobium and tantalum have virtually no cationic chemistry, but form several kinds of anionic species. Such behaviour is in particular important in extraction mechanism of all types of extracting agents. The tendency of both metals to form polynuclear species, dependent on metal concentration, pH, ligand type and electronegativity, is well known. However, even in systems such as oxalic and tartaric acid solutions, the characterisation of anionic metal complexes has not been fully established (1).
