Lanthanum, cerium, neodymium, samarium, europium, gadolinium, dysprosium, erbium, ytterbium, lutetium and yttrium have been determined in 8 international rock standards by inductively coupled plasma atomic emission spectrometry (ICP-AES) without prior ion-exchange separation and preconcentration. The results for La, Ce, Nd, Eu, Dy, Yb and Y were in good agreement with the reported values, whereas those for Sm, Gd, Er and Lu were less accurate. However, the results for Sm, Gd, Er and Lu can also be used for studies of petrogenesis.
采用电感耦合等离子体原子发射光谱法（ICP-AES），无需事先进行离子交换分离和预富集，测定了8种国际岩石标准物质中的镧、铈、钕、钐、铕、钆、镝、铒、镱、镥和钇。镧、铈、钕、铕、镝、镱和钇的测定结果与报道值吻合良好，而钐、钆、铒和镥的测定结果准确性稍差。不过，钐、钆、铒和镥的测定结果也可用于岩石成因研究。
