在铀的工艺与研究中遇到有关铀的分析,基本上可分为四类:(1)不含干扰性元素的试料中微量铀的分析;(2)含有干扰性元素的试料中微量铀的分析;(3)不含有干扰性元素的试料中大量铀的分析;(4)含干扰性元素的试料中大量铀的分析,为了解决这些类型的分析问题,可以用某些仪器分析,也可采用化学分析,特别是大量铀的分析,以化学法的准确度为最高。对第一类,我们基本上采用K_4Fe(CN)_6比色法;对第二类,我们采用的沃尔可夫的钒酸铵法。对大量铀的分析,我们进行了一些工作,讨论如下:
Analysis of uranium encountered in uranium processes and studies can be divided into four broad categories: (1) Analysis of trace amounts of uranium in samples that do not contain interfering elements; (2) In samples containing interfering elements Analysis of trace amounts of uranium; (3) Analysis of large quantities of uranium in samples that do not contain interfering elements; (4) Analysis of large quantities of uranium in samples containing interfering elements; and to address these types of analytical problems, Instrument analysis, but also the use of chemical analysis, especially a lot of uranium analysis, the highest accuracy of the chemical method. For the first class, we basically use the K_4Fe (CN) _6 colorimetric method; for the second class, we use the Volkoff ammonium vanadate method. We have done some work on the analysis of a large amount of uranium and discussed the following:
