Title

The aqueous solution thermodynamics of tantalum under conditions of environmental and biological interest

Abstract Relatively little information is available in the literature regarding the speciation and solubility of tantalum in aqueous solutions. The available thermodynamic data have been critically evaluated and entered into a thermodynamic database. The JESS suite of computer programs has been used to achieve thermodynamic consistency and provide a critically-selected set of equilibrium constants that can later be used for modelling purposes. The utility of the resulting set is limited by a lack of adequate data. Gathered evidence suggests however that tantalum concentrations in freshwater are probably controlled by the changing solubility of tantalum oxide solid as it ages.
