本文叙述了应用电感耦合等离子体发射光谱法同时定量测定硅酸盐岩石中主要、次要组分:Si、Al、Ca、Mg、Fe、Mn、Ti、P、Sr、Ba、Cu、Zn、V、Zr、Cr、Y、Yb等十七个元素的分析过程、元素间的干扰效应及其校正方法。本方法使用岛津ICPQ-100型等离子体光量计,样品溶液不经去溶,在同一份溶液中同时测定上述元素,获得了较好的准确度和精密度。特别是高含量硅(30—80％)测定的相对标准偏差小于0.5％。
This paper describes the simultaneous determination of major and minor components in silicate rocks by inductively coupled plasma atomic emission spectrometry: Si, Al, Ca, Mg, Fe, Mn, Ti, P, Sr, Ba, Cu, Zn, V, Zr, Cr, Y, Yb and other seventeen elements of the analysis process, the interference between elements and the correction method. The method uses Shimadzu ICPQ-100 type plasma spectrometer, the sample solution is not desolvated, and the same solution is simultaneously measured in the same solution to obtain better accuracy and precision. In particular, the relative standard deviation of the high content of silicon (30-80%) was less than 0.5%.
