铀在特定场址地下水中存在和迁移形态研究及其沉积热力学分析

Thermodynamics Analysis of Uranium's Chemical Species, Migration and Deposition in Groundwater of a Certain Place

摘要: 将化学热力学平衡分析模式与地球化学条件相结合,应用铀元素水文地球化学迁移形式热力学分析方法,计算出某特定场址地下水中铀的化学形态和迁移形态。结果表明:UO2(CO3)2-2占84.1%,UO2(CO3)0占8.7%,UO2(CO3)4-3占6.5%。

Abstract: The thermodynamics analysis system of U migrating by hydrological and geochemical species is got by combining the thermodynamics balance analysis mode and the geochemical condition. The (uranium's) chemical species and migration species in groundwater of a certain place have been calculated. The result shows: UO_2(CO_3)~(2-)_2 is 84.1%, UO_2(CO_3)~0 is 8.7% and UO_2(CO_3)~(4-)_3 is 6.5%.
