| 摘 要： | 以我国高放废物地质处置库重点研究区甘肃北山、西南某地和新疆准噶尔盆地地下水为对象,运用PHREEQC程序分别计算了不同地下水中铀种态的含量,并讨论了pH值、温度对铀种态分布的影响。结果表明:铀种态主要取决于地下水的化学组分,pH值、温度等物理因素对铀在地下水中的种态分布也有显著影响。因此,处置库选址需要考虑地下水的组成以及pH值和温度等因素的影响。

| Abstract: | PHREEQC software was used to study the chemical species of uranium based on the chemical composition of groundwater in Beishan, Southwest China and Junggar Basin in Xinjiang. The effects of pH, and temperature on the species distribution of uranium were studied. The results show that the species of uranium in groundwater mainly depend on the chemical composition of groundwater. Furthermore, pH, temperature and other physical factors also have a significant impact on the species distribution of uranium in the groundwater. Therefore, groundwater component should be given consideration in the repository site selection, followed by taking a consideration on groundwater of pH and temperature as well as other factors. |
