Thermodynamic studies on the solubility of actinides in the presence of organic acids related to geological disposal

Kobayashi, Taishi*; Teshima, Takeshi*; Wang, P.*; Sasaki, Takayuki*; Kitamura, Akira  

We focused on the complexation of U(IV) and U(VI) with isosaccharinic acid (ISA) and measured U(IV) and U(VI) solubility in the presence of ISA. The solubility dependences on hydrogen ion concentration (pHc) and ISA concentration revealed the dominant U(IV) and U(VI) ISA complexes and determined their formation constants. Furthermore, the solubility of Zr(IV), as an analogous of An(IV), in the presence of organic acids with different number of hydroxyl groups were investigated to elucidate the strong complexation ability of ISA.
