Consistent set of thermodynamic constants for americium (III) species with hydroxyl and carbonate

PDF Version Also Available for Download.

Description

A consistent set of thermodynamic constants for aqueous species and compounds of Am(III) with hydroxyl and carbonate ligands has been developed. The procedure used to develop these constants involved establishing a value for one formation constant at a time in a sequential order, starting with the hydrolysis products and hydroxide solids, and then proceeding to carbonate species. The EQ3NR chemical-equilibrium model was used to test the constants developed. These constants are consistent with most of the experimental data that form their basis; however, considerable uncertainty still exists in some aspects of the Am(III) data.
