引言分析铀矿中轴含量的分光光度法有:碱性过氧氢法、二苯甲醯基代甲烷法、硫氰酸铵法和8-羟基喹啉法等,一般来说,分光光度法的主要困难在于干扰元素过多,最近,尼兹耳(Nietzel)和代·塞萨(De Sesa)提出对硫氰酸铵法的改良,无论在颜色的稳定性和干扰元素的消除方面都有显著的改进。8-羟基喹啉一氯仿法的干扰元素很多,例如,铁、铝、锆、钍、铋和其他阳离子(Ba~(+2),Ca~(+2),Cd~(+2),Ce~(+2),Co~(+2),Cu~(+2),La~(+2),Mg~(+2),Mn~(+2),Ni~(+2),Pb~(+2),Sr~(+2)和Zn~(+2))都将产生干扰。这是一
Introduction Analysis of uranium shaft content of the spectrophotometry are: alkaline hydrogen peroxide, benzhydryl methyl methane method, ammonium thiocyanate method and 8-hydroxyquinoline law, in general, spectrophotometry The main difficulty is that there are too many interfering elements. Recently, Nietzel and De Sesa proposed improvements to the ammonium thiocyanate method both in terms of color stability and elimination of interfering elements Significant improvement. The 8-hydroxyquinoline-chloroform method has many interference elements such as iron, aluminum, zirconium, thorium, bismuth and other cations (Ba 2+, Ca 2+, Cd 2+, Ce (+2), Cu 2+, La 2+, Mg 2+, Mn 2+, Ni 2+, Pb 2+, (+2), Sr ~ (+2) and Zn ~ (+2)) will cause interference. this is one
