摘　　要：建立了ICP-AES法直接测定U-Zr合金中Zr含量的分析方法。该方法用王水-氢氟酸溶解U-Zr合金切屑样,制成试样,用光谱仪直接测定U-Zr合金中Zr含量。取样量为25 mg时,Zr的测量范围为2.0%~20.0%,方法回收率在98%~102%之间,测量结果的相对标准偏差不大于2%。In order to meet the research demand of U-Zr alloy,an analytical method was developed to detect the concentration of Zr in U-Zr alloy. First,the U-Zr alloy sample was dissolved in royal water-hydrofluoric acid solution,and then the direct detection of Zr concentration in U-Zr alloy was realized by ICP-AES. When 25 mg U-Zr sample was added,this proposed method enabled the detection of Zr in a wide linear range from 2. 00% to20. 00% with the recoveries from 98% to 102%,and RSD less than 2%.
