研究给出了分光光度法和X射线荧光法分析乏燃料后处理模拟工艺料液中锆的适用条件和分析步骤。对经TBP萃取过或从TBP中反萃制备的样品 ,用二甲酚橙或偶氮砷Ⅲ做显色剂的分光光度法分析是不可行的 ,建议采用X射线荧光法分析样品中的锆。
The application of spectrophotometry and X-ray fluorescence spectrometry for the analysis of zirconium in simulated process feedstock of spent fuel was given. For samples prepared by TBP extraction or back-extraction from TBP, spectrophotometric analysis using xylenol orange or azo-arsenic III as a chromogenic reagent is not feasible and it is recommended to analyze the zirconium in the sample by X-ray fluorescence .
