| 摘 要： | 用Fe(OH)2共沉淀淡水样中的铀和钍，经硝酸溶解后，用^235N－环己烷萃取铀钍，在盐酸介质中分光光度法分别测定飞来峡水库水样铀、钍的含量。结果表明，铀、钍的回收率稳定在80％以上，方法稳定可靠；飞来峡水利枢纽建成后库区水体中铀、钍的含量维持在以前的水平。

| Abstract: | U and Th in fresh water from Feilaixia Reservoir were co precipitated with Fe(OH) 3, dissolved by HNO 3, extracted by 235 N cyclohexane,and determined by Spectrophotometric Method.The results showed that the recoveries of U and Th were above 80%.The method is stable and reliable.There was no change in contents of U and Th in water samples compared with the results before the project. |
