近代技术的发展对稀土分析的灵敏度和准确度提出愈来愈高的要求,用原子发射光谱法测定稀土氧化物中非稀土杂质时,利用载体分馏是普遍和有效的途径,一般可以使测定下限比直接光谱法降低约一个数量级,因此广为国内外分析工作者所采用。文献报导的载体有混合载体AgF-Ga_2O_3、 The development of modern technology puts forward higher and higher requirements on the sensitivity and accuracy of rare earth analysis. When using atomic emission spectrometry to measure the non-rare earth impurities in rare earth oxides, the use of carrier fractionation is a common and effective way, and the lower limit of determination It is about one order of magnitude lower than direct spectroscopy and is therefore widely used by analysts at home and abroad. The vectors reported in the literature are mixed carrier AgF-Ga 2 O 3,
