摘要
化探样品中硼、铅、锡、铌、镧、锆、钇的光谱测定已有报导,但这些方法仅适应于含钙不高的硅酸盐样品的分析。实际上,在化探样品分析中常会遇到不少的含钙较高的样品,为适应这些样品的分析需要,本文通过选择合适的缓冲剂和内标,较好地消除了钙的影响,当CaO含量在15—
In this method, Na_2SO_4, SiO_2, Fe_2O_3 and graphite powder are used as buffer. Germanium, Erbium and Hafnium are selected as internal Standard. Emission spectrometry is used to determine B, Pb Sn, Nb, La, Zr and Y in high-calcium geochemical samples. The detection limits, accuracy and precision meet the demand for regional geochemical survey.
