| 520 | 3 | |a The solubility of Pu(VI) hydrous oxide was measured in the pHc range from 4 to 5.5 at 25±1°C in a NaClO4 solution containing O3 gas. The experiment was carried out by oversaturation and undersaturation methods at ionic strength I=0.1, 0.5 and 1.0. The concentration of Pu(VI) was measured by α-spectrometry and UV/visible spectrophotometry, and the equilibrium constant of the reaction, PuO2(OH)2=PuO22+ + 2 OH-, was obtained. From the obtained results, the solubility products (Ksp) of Pu hydrous oxide at I=0.1, 0.5 and 1.0 were determined. The experimental values were extrapolated to the standard state (I=0) by using the specific interaction theory (SIT), and the solubility product of Pu hydrous oxide was determined to be log Ksp°=-22.88±0.39. The ion interaction coefficient (PuO22+, ClO4-) was also evaluated to be 0.30±0.09. | |
