| 摘 要： | 研究了铀酸盐型黄饼硝酸不溶渣中铀的分光光度测定法.不溶渣中的铀在碱性介质中与过氧化氢反应生成稳定的黄色过铀酸钠,在波长420 nm处,测定吸光度,从而测得渣中铀的质量分数.方法回收率为96.6％～106％,相对标准偏差小于1％,适用于厂矿对铀酸盐型黄饼硝酸不溶渣中铀质量分数的测定.

| Abstract: | When nitric acid-insoluble residues produced in dissolution of uranate type yellowcake are in the alkaline medium,uranium in the residue reacts with hydrogen peroxide,and a stable yellow so-dium peroxyuranate is formed.Its absorbance was measured at 420 nm in wavelength,thereby,ura-nium content in the residues can be measured.The recovery of the method is 96.6%-106%,and the relative standard deviation is less than 1%. |
