摘要
为满足大量U-Zr合金常规分析的需求,研究了用能量色散X射线荧光光谱(EDXRF)法测定U-Zr合金中Zr的含量。切屑样品经溶解、转移、烘干等操作后,制备出薄层样品,用于EDXRF测量。与传统方法相比,本方法简便、快速、准确,适用于Zr含量在6%~18%(质量分数,下同)范围的U-Zr合金样品的Zr含量测定,测量结果的相对标准偏差(n=6)不大于1.0%,方法扩展不确定度(k=2)不大于3%。
To meet the demand of a large amount of U-Zr alloy routine analysis, energy dispersion X-ray fluorescence was used to determine zirconium content in U-Zr alloy. The thin-layer samples were prepared through dissolution, transferring and drying for EDXRE determination. Compared to traditional methods, this method is of simplicity, rapidness and accuracy. It can be used to determine the Zr content in the range of 6%~18%（mass fraction） in U-Zr alloy. The relative standard deviation（RSD）（n=6） is not above 1.0%. The extended-uncertainty（k=2） is not above 3%.
