Stability constants of uranium(IV)-α-isosaccharinic acid and gluconic acid complexes
journal contribution
posted on 2007-12-21, 15:11 authored by Peter Warwick, Nick Evans, Tony Hall, Sarah VinesConditional and pH independent stability constants
have been determined for U(IV) α-isosaccharinic acid
(ISA) and gluconic acid (Gl) complexes, under anaerobic
and carbonate-free conditions, from pH 3 to 14. The constants
are needed for nuclear waste repository performance
assessment purposes. The constants were obtained by developing
an approach based on the solubility product of
amorphous UO2 ·2H2O. The derived pH independent log β
values for U(OH)4ISA and U(OH)4Gl were 49±2 and 50±1
respectively.
