Brukl等较早地报告了氧化铕中钐的测定;Kustas等以溶液干渣法测定了氧化铕中14个稀土元素,可对98.8%纯度的氧化铕进行快速测定;Osumi等报导了在氩气气氛中直流电弧粉末法测定氧化铕中稀土元素;Murty采用氧气气氛直流电弧粉末法测定氧化铕中钕、钐、钆、铽、镝等五个稀土元素。这些方法对于测定高纯氧化铕中14个稀土元素都有不足之处。 Brukl et al. Reported earlier the determination of samarium in europium oxide; Kustas et al. Determined 14 rare earth elements in europium oxide by the solution dry-slag method, enabling the rapid determination of 98.8% purity of europium oxide; Osumi et al. Determination of Rare Earth Elements in Europium Oxide by DC Arc Powder Method in Atmosphere; Five Rare Earth Elements such as Neodymium, Samarium, Gadolinium, Terbium and Dysprosium in Europium Oxide were Determined by Oxygen Atmosphere DC Arc Powder Method. These methods are inadequate for the determination of 14 rare earth elements in high purity europium oxide.
