本文是朱詠煊同志在岩矿中微量元素分析交流会上提交的报告。提出了作者对分光光度法在微量元素分析中应用前景的看法。现发表于下,以供有关方面参考。岩石分析中习惯上把硅、钛、铝、铁、锰、钙、镁、钠、钾、氢、碳、磷的氧化物,以及氟、硫等成分以外的元素成分称为微量元素。有人则把试样中浓度低于0.1％或0.01％的成分称为微量元素;或再划分为微量成分、痕量成分及超痕量成分。 This article is a report submitted by Comrade Zhu Yongli at the exchange meeting of trace elements analysis in rocks and mines. Put forward the author of spectrophotometry in the analysis of trace elements in the application prospects. Now published in the next, for the relevant reference. In rock analysis, the elemental components other than silicon, titanium, aluminum, iron, manganese, calcium, magnesium, sodium, potassium, hydrogen, carbon and phosphorus oxides and other components such as fluorine and sulfur are traditionally called trace elements. Some people put the sample concentration of less than 0.1% or 0.01% of the ingredients as trace elements; or subdivided into trace components, trace components and ultra-trace components.
