Hydrolysis reactions and carbonate complexation of americium(III) in natural aquatic systems

Creators

Description

The hydrolysis reaction and carbonate complexation of the Am3+ and Eu3+ have been investigated in the pH region of 3 - 13 by solubility measurements at the ionic strength of 0.1 and 25 +- 0.50C. The solubility products of M(OH)3, M(OH)CO3 and M2(CO3)3 and the stability constants for the species Msub(x)(OH)sub(y)(CO3)sub(z), varying x = 1 - 3, y = 0 - 4 and z = 0 - 3, are determined. The results are compared with the literature data for M3+ ions. (orig.)
