摘　　要：试样经高温灼烧氧化后,采用硝酸和盐酸溶解稀土金属氧化物干渣。研究了核纯石墨中Sm,Eu,Gd和Dy的电感耦合等离子体原子发射光谱法(ICP-AES)。对影响测定的各种因素进行了较详细的试验研究,确定了测定最佳条件。当称样量为2.0g时,方法平均回收率在90%～102%之间,相对标准偏差(RSD,n=6)优于8.3%。方法操作简便、快速、准确、精密度好。The authors paper researched inductively coupled plasma atomic emission spectrometry method for the determination of Sm,Eu,Gd and Dy in nuclear grade graphite.The sample cauterized in high temperature was dissolved in HCl and HNO3.The authors researched all kinds of factors which influence determination and established this method.When the weight of sample was 2.0 g,the recovery was between 90% and 102%,and the relative standard deviation was better than 8.3%。
