摘要: 采用衬钽片的石墨管,以石墨炉原子吸收光谱法测定了氧化钐和氧化钆中的铕。探讨了盐酸浓度,基体钐和针对铕测定的影响;考察了方法的灵敏度和精密度;建立了灵敏准确易于掌握的分析方法。 本方法不需要预先分离基体,样品经溶解后即可直接进行分析。

Abstract: In this paper a simple, sensitive method for the determination of eu-ropium in samarium and gadolinium oxides using a graphite tube lined withtantalum foil is described. The effects of hydrochloric acid concentrationand samarium and gadolinium matrix are discussed.The method can be useddirectly for the sample analysis without predissociation of matrix.
