在混合稀土分离流程的铒-铥分组研究过程中,要求检测混合稀土中的铥、镱和镥的含量(铥和镥为0.5～5%,镱为4～15%)。这样高的含量用普通的发射光谱法是不容易得到准确的分析结果的。本方法的目的在于力求准确,鉴于载体的作用,我们在缓冲剂中加入5%的氯化银,获得了良好的再现性。方法的相对标准偏差为铥和镥4.6%,镱7.0%。 In the erbium-铥 sub-grouping study of mixed rare earth separation processes, the contents of 铥, ytterbium and 镥 (铥 and 镥 0.5 to 5%, ytterbium 4 to 15%) in mixed rare earths are required. Such a high content is not easy to get accurate analytical results by ordinary emission spectrometry. The purpose of this method is to be accurate. Given the effect of the carrier, we add 5% silver chloride to the buffer and achieve good reproducibility. The relative standard deviation of the method was 4.6% for 铥 and 镥 and 7.0% for ytterbium.
