摘　　要：本法采用237-季按萃取树脂，利用车取色谱分离技术，将U3O8。标样中铀与诗测杂质元素在6．5mol／LHNO3。介质中定量分离后，用IRIS／AP全谱直读光谱仪同时测定Al、Mn、Mo和Ti，分析结果均落在标准值的置信区间内，RSD＜5％。The 237-quaternary ammoniurn extraction resin Chromatography was used to separation 4 trace elements in U3O8, reference sample. The sample was dissolved in 6. 5 mo1/Ix HNO3,and the uranium was -separated by (thromatographric Col-umn. The 4 trace elements Al, Mn,Mo and Ti Containing in the elutriant were determined useing lRIS/AP plasrna speotrorneter.The analytical results obtained for all elements were in agreement with the standard values. The RSDs (n = 6 )for the determina-tions were less than 5 %.
