将盐湖水中主要阴、阳离子的浓度输入PHREEQC形态模拟计算软件,通过pH值、温度、离子强度等因素改变对铀形态的影响计算得出:铀离子与碳酸根离子结合的络合物是盐湖水中铀的主要存在形态,并会随着溶液pH值的变化而改变。盐湖水的pH值在8~10之间变化时,UO2( CO3)4-3为铀酰离子在盐湖水中的主要存在形态。
將鹽湖水中主要陰、暘離子的濃度輸入PHREEQC形態模擬計算軟件,通過pH值、溫度、離子彊度等因素改變對鈾形態的影響計算得齣:鈾離子與碳痠根離子結閤的絡閤物是鹽湖水中鈾的主要存在形態,併會隨著溶液pH值的變化而改變。鹽湖水的pH值在8~10之間變化時,UO2( CO3)4-3為鈾酰離子在鹽湖水中的主要存在形態。

The content of main anion and cation in the saline lake water were inputed into PHREEQC simu-lation software for analog computation.By changing the factors such as pH, temperature, ionic strength, the im-pact 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 .
