| The content of main anion and cation in the saline lake water were inputed into PHREEQC simulation software for analog computation. By changing the factors such as pH, temperature, ionic strength, the impact on uranium chemical speciation is calculated, resulting that the main form existent in the lake was a complex of uranium and carbonate ion, which could vary with the pH of the solution. Generally, the pH of the lake water ranges from 6 to 8, and the main form of uranyl ion in the saline lake water is UO2(CO3)4-3. |
