Sažetak:
Precipitation diagrams by using the data obtained in experiments with direct mixing of uranyl ion ([UO2]2+) and hydrogen peroxide were constructed. Three days after mixing the system, the equilibrium was established at [H2O2]tot > [UO2]tot concentration region, resulting in stability of the concentration boundary. From this boundary condition, the solubility product (Ksp = [UO22+] × [O22-]) was defined. The solubility product mean value was found to be (1.32+-0.02)×10-36 mol L-1. From the solubility border, where equilibrium was established, i. e. at [UO22+] = 1.4×10-4 mol L-1, the heterogeneous distribution diagrams of uranyl species, including the solid phase, were calculated.
