| 摘 要： | 用１－苯基－３－甲基－４－苯甲酰基吡唑啉酮－５（ＰＭＢＰ）作萃取剂，２３４Ｔｈ为示踪剂，对在ＨＮＯ３介质中用ＰＭＢＰ－苯萃取钍的条件实验进行了研究。在条件实验的基础上提出了一个从中能１８Ｏ离子照过的天然铀样品中简便、快速地分离钍的化学流程。钍样品的Ｙ射线谱显示该流程能去除绝大多数产物元素，特别是Ｕ、Ｃｅ和Ｉ的沾污。 |

| Abstract: | The experimental conditions for the extraction of thorium by using PMBP as extractant and 234Th as tracer in the nitric acid solution were investigated. Based on the experiments, a chemical procedure used for rapidly separating thorium from the natural uranium irradiated by 18O ions was developed. The r spectrum of the thorium fraction shows that the most of the reaction products, especially U, Ce and I can be completely removed by using the procedure. |
