感耦等离子体发射光谱法测定纯氧化镧中稀土和非稀土杂质

Determination of Impurities in Pure Lanthanum Oxide by Inductivel y-Coupled Plasma Emission Spectrometry

  • 摘要: 研究了用感耦等离子体发射光谱(ICP-AES)测定纯氧化镧中Ce,Pr,Nd,Sm,Y,Fe,Al,Ca,Mg和Si10个杂质元素的方法。考察了基体镧的光谱干扰,共存元素间光谱干扰及校正方法,方法检出限为0.0005-0.039μg/ml;标准加入量1μg/ml时,回收率为95%-106%;10μg/ml的标准溶液,测定10次,RSD为0.24%-1.01%。方法简单,快速,不震分离富集,适用于氧
