| 摘 要： | 在水浴加热条件下，用硫酸氢根将吸附在树脂上的铀酰离子和硝酸根离子置换到液相中，之后分别采用亚钛法、分光光度法进行测定。结果表明，该方法测定铀和硝酸根的相对标准偏差都小于2％，分析结果与高温灰化法测定铀及氢氧化钠浸煮法测定硝酸根的结果基本一致。

| Abstract: | Heated in water bath, uranyl ion and nitrate radical adsorbed on resin are replaced into solution by sodium bisulfate, then are determined by titanous method and spectrophotometry, respectively. The results indicated that the relatively standard deviations of determination for uranium and nitrate radical are less than 2%. The determination results by the method are consistent with the high temperature cineration for uranium and the digestion with sodium hydroxide for nitrate radical. |
