摘要: 本文从量子化学角度讨论了导数分光光度法中重叠谱带的相互干扰,得到了一些理论标准和误差公式,并通过实验数据作了验证。通过理论分析,我们用三阶导数光谱来测定U(Ⅵ),Th的干扰得到了限制,最大相对误差为11%。

Abstract: This paper, from the quantitative angle, discusses the interferences, of overlap bands with each other in derivative spectrophotometry. Some theoretical criteria and formulas of error were obtained and demonstrated by the experimental data. By means of theoretical analysis, we selected the third derivative spectra for the determination of uranium (Ⅵ). The interference of Th is limited. The maximum relative error is 11%.
